The output amplifier has rail-to-rail operation. OUT 2 V B Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation. OUT 3 GND Ground. Reference point for all circuitry on the part. 4 LDAC Pulsing this pin low allows any or all DAC registers to be updated if the input registers have new data. This allows simultaneous update of all DAC outputs. Alternatively, this pin can be tied permanently low. 5 CLR Asynchronous Clear Input. The CLR input is falling edge sensitive. While CLR is low, all LDAC pulses are ignored. When CLR is activated, zero scale is loaded to all input and DAC registers. This clears the output to 0 V. The part exits clear code mode on the 24th falling edge of the next write to the part. If CLR is activated during a write sequence, the write is aborted. 6 SYNC Level-Triggered Control Input (Active Low). This is the frame synchronization signal for the input data. When SYNC goes low, it enables the input shift register, and data is transferred in on the falling edges of the following clocks. The DAC is updated following the 24th clock cycle unless SYNC is taken high before this edge, in which case the rising edge of SYNC acts as an interrupt and the write sequence is ignored by the DAC. 7 SCLK Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock input. Data can be transferred at rates up to 50 MHz. 8 DIN Serial Data Input. This device has a 24-bit shift register. Data is clocked into the register on the falling edge of the serial clock input. 9 V Power Supply Input. These parts can be operated from 2.7 V to 5.5 V, and the supply should be decoupled with DD a 10 μF capacitor in parallel with a 0.1 μF capacitor to GND. 10 V /V Common Reference Input/Reference Output. When the internal reference is selected, this is the reference output REFIN REFOUT pin. When using an external reference, this is the reference input pin. The default for this pin is a reference input. Rev. G | Page 10 of 32

Data Sheet AD5623R/AD5643R/AD5663R TERMINOLOGY Relative Accuracy or Integral Nonlinearity (INL) DC Power Supply Rejection Ratio (PSRR) For the DAC, relative accuracy or integral nonlinearity is a PSRR indicates how the output of the DAC is affected by measurement of the maximum deviation, in LSBs, from a changes in the supply voltage. PSRR is the ratio of the change in straight line passing through the endpoints of the DAC transfer VOUT to a change in VDD for full-scale output of the DAC. It function. A typical INL vs. code plot is shown in Figure 5. is measured in dB. VREF is held at 2 V, and VDD is varied by ±10%. Differential Nonlinearity (DNL) Differential nonlinearity (DNL) is the difference between the Output Voltage Settling Time measured change and the ideal 1 LSB change between any two Output voltage settling time is the amount of time it takes for adjacent codes. A specified differential nonlinearity of ±1 LSB the output of a DAC to settle to a specified level for a 1/4 to 3/4 maximum ensures monotonicity. This DAC is guaranteed full-scale input change and is measured from the 24th falling monotonic by design. A typical DNL vs. code plot is shown in edge of SCLK. Figure 9. Digital-to-Analog Glitch Impulse Zero-Scale Error The impulse injected into the analog output when the input Zero-scale error is the measurement of the output error when code in the DAC register changes state. It is normally specified zero code (0x0000) is loaded to the DAC register. Ideally, the as the area of the glitch in nV-sec and is measured when the output should be 0 V. The zero-scale error is always positive in digital input code is changed by 1 LSB at the major carry the AD5623R/AD5643R/AD5663R because the output of the transition (0x7FFF to 0x8000). See Figure 38. DAC cannot go below 0 V. It is due to a combination of the Digital Feedthrough offset errors in the DAC and the output amplifier. Zero-scale A measure of the impulse injected into the analog output of the error is expressed in mV. A plot of zero-scale error vs. DAC from the digital inputs of the DAC, digital feedthrough is temperature is shown in Figure 26. measured when the DAC output is not updated. It is specified Full-Scale Error in nV-sec, and it is measured with a full-scale code change on Full-scale error is the measurement of the output error when the data bus, that is, from all 0s to all 1s and vice versa. full-scale code (0xFFFF) is loaded into the DAC register.

It is expressed in Gain Error decibels (dB). Gain error is a measure of the span error of the DAC. It is the Noise Spectral Density deviation in slope of the DAC transfer characteristic from ideal, Noise spectral density is a measurement of the internally expressed as a percent of the full-scale range. generated random noise. Random noise is characterized as a Zero-Scale Error Drift spectral density (nV/√Hz). It is measured by loading the DAC Zero-scale error drift is the measurement of the change in zero- to midscale and measuring noise at the output. A plot of noise scale error with a change in temperature. It is expressed in spectral density is shown in Figure 44. microvolts/°C (μV/°C). DC Crosstalk Gain Temperature Coefficient DC crosstalk is the dc change in the output level of one DAC in Gain temperature coefficient is a measurement of the change in response to a change in the output of another DAC. It is gain error with changes in temperature. It is expressed in (ppm measured with a full-scale output change on one DAC (or soft of full-scale range)/°C. power-down and power-up) while monitoring another DAC kept at midscale. It is expressed in microvolts (μV). Offset Error DC crosstalk due to load current change is a measure of the Offset error is a measure of the difference between V (actual) OUT impact that a change in load current on one DAC has to and V (ideal) expressed in mV in the linear region of the OUT another DAC kept at midscale.

AD5623R/AD5643R/AD5663R Data Sheet Digital Crosstalk Multiplying Bandwidth Digital crosstalk is the glitch impulse transferred to the output The amplifiers within the DAC have a finite bandwidth. The of one DAC at midscale in response to a full-scale code change multiplying bandwidth is a measure of this. A sine wave on the (all 0s to all 1s and vice versa) in the input register of another reference (with full-scale code loaded to the DAC) appears on DAC. It is measured in standalone mode and is expressed the output. The multiplying bandwidth is the frequency at in nanovolts-second (nV-sec). which the output amplitude falls to 3 dB below the input. Analog Crosstalk Total Harmonic Distortion (THD) Analog crosstalk is the glitch impulse transferred to the output Total harmonic distortion is the difference between an ideal of one DAC due to a change in the output of another DAC. It is sine wave and its attenuated version using the DAC. The sine measured by loading one of the input registers with a full-scale wave is used as the reference for the DAC, and the THD is a code change (all 0s to all 1s and vice versa) while keeping LDAC measurement of the harmonics present on the DAC output. high. Then pulse LDAC low and monitor the output of the DAC It is measured in decibels (dB). whose digital code was not changed. The area of the glitch is expressed in nanovolts-second (nV-sec). DAC-to-DAC Crosstalk DAC-to-DAC crosstalk is the glitch impulse transferred to the output of one DAC due to a digital code change and subsequent output change of another DAC. This includes both digital and analog crosstalk. It is measured by loading one of the DACs with a full-scale code change (all 0s to all 1s and vice versa) with LDAC low and monitoring the output of another DAC. The energy of the glitch is expressed in nanovolts-second (nV-sec). Rev. G | Page 20 of 32

When using the internal reference, it is recommended that a 100 nF capacitor be placed between 0 to 4095 for AD5623R (12-bit) reference output and GND for reference stability. 0 to 16,383 for AD5643R (14-bit) 0 to 65,535 for AD5663R (16-bit) EXTERNAL REFERENCE N is the DAC resolution.

The data bits are transferred to the DAC register on the 24th falling edge of SCLK. In a normal write sequence, the SYNC line is kept low for at least 24 falling edges of SCLK, and the DAC is updated on the 24th falling edge. However, if SYNC is brought high before the 24th falling edge, this acts as an interrupt to the write sequence. The shift register is reset, and the write sequence is seen as invalid. Neither an update of the DAC register contents nor a change in the operating mode occurs (see Figure 54).
