A voltage in the range of 7.5 V to 16.5 V can be connected to this pin. DD V must be decoupled to AGND. DD 4 RESET Active Low Reset. Asserting this pin returns the AD5760 to its power-on status. 6 CLR Active Low Input. Asserting this pin sets the DAC register to a user defined value (see Table 12) and updates the DAC output. The output value depends on the DAC register coding that is being used, either binary or twos complement. 7 LDAC Active Low Load DAC Logic Input. This pin is used to update the DAC register and, consequently, the analog output. When tied permanently low, the output is updated on the rising edge of SYNC. If LDAC is held high during the write cycle, the input register is updated, but the output update is held off until the falling edge of LDAC. Do not leave the LDAC pin unconnected. 8 V Digital Supply. Voltage range is from 2.7 V to 5.5 V. V should be decoupled to DGND. CC CC 9 IOV Digital Interface Supply. Digital threshold levels are referenced to the voltage applied to this pin. Voltage CC range is from 1.71 V to 5.5 V. 10, 21, 22, 23 DNC Do Not Connect. Do not connect to these pins. 11 SDO Serial Data Output. Data is clocked out on the rising edge of the serial clock input. 12 SDIN Serial Data Input. This device has a 24-bit input shift register. Data is clocked into the register on the falling edge of the serial clock input. 13 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 of up to 35 MHz. 14 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 then transferred in on the falling edges of the following clocks. The DAC is updated on the rising edge of SYNC. 15 DGND Ground Reference Pin for Digital Circuitry. 16 V Negative Reference Voltage Input. REFN 17, 18 V Negative Analog Supply Connection. A voltage in the range of −16.5 V to −2.5 V can be connected to this SS pin. V must be decoupled to AGND.

For fast settling applications, a high speed INL error vs. code plot is shown in Figure 5. buffer amplifier is required to buffer the load from the 3.4 kΩ output impedance of the AD5760, in which case, it is the Differential Nonlinearity (DNL) amplifier that determines the settling time. Differential nonlinearity is the difference between the measured change and the ideal 1 LSB change between any two adjacent Digital-to-Analog Glitch Impulse codes. A specified differential nonlinearity of ±1 LSB maximum Digital-to-analog glitch impulse is the impulse injected into the ensures monotonicity. This DAC is guaranteed monotonic.

It is specified as the area of the glitch in nV-sec (see Zero-Scale Error Figure 48). Zero-scale error is a measure of the output error when zero-scale code (0x00000) is loaded to the DAC register. Ideally, the output Digital Feedthrough voltage should be VREFN. Zero-scale error is expressed in LSBs. Digital feedthrough is a measure of the impulse injected into the analog output of the DAC from the digital inputs of the Zero-Scale Error Temperature Coefficient DAC but is measured when the DAC output is not updated.

AD5760 Data Sheet THEORY OF OPERATION The AD5760 is a high accuracy, fast settling, single, 16-bit, R R R VOUT serial input, voltage output DAC. It operates from a VDD supply 2R 2R 2R... 2R 2R 2R... 2R voltage of 7.5 V to 16.5 V and a VSS supply of −16.5 V to −2.5 V. VREFP S0 S1... S9 E62 E61...

DAC Ladder Structure Serial Interface The architecture of the AD5760 consists of two matched DAC SERIAL INTERFACE sections. A simplified circuit diagram is shown in Figure 49. The six MSBs of the 16-bit data-word are decoded to drive The AD5760 has a 3-wire serial interface (SYNC, SCLK, and 63 switches, E0 to E62. Each of these switches connects one of SDIN) that is compatible with SPI, QSPI, and MICROWIRE 63 matched resistors to either the buffered V or buffered interface standards, as well as most DSPs (see Figure 2 for a REFP V voltage.

The AD5760 can be reset to its power-on state by two means: The input shift register is updated on the rising edge of SYNC. either by asserting the RESET pin or by using the reset function For another serial transfer to take place, SYNC must be brought in the software control register (see Table 13).
