PGA2311 SBOS218D–DECEMBER2001–REVISEDMAY2016 www.ti.com 7 Detailed Description 7.1 Overview The PGA2311 is a stereo audio volume control that can be used in a wide array of professional and consumer audioequipment.ThePGA2311isfabricatedinasub-micronCMOSprocess. The heart of the PGA2311 is a resistor network, an analog switch array, and a high-performance operational amplifier stage. The switches select taps in the resistor network that determine the gain of the amplifier stage. Switch selections are programmed using a serial control port. The serial port allows connection to a wide variety ofhostcontrollers.TheFunctionalBlockDiagramsectionshowsamodeldiagramofthePGA2311. 7.2 Functional Block Diagram Copyright © 2016,Texas Instruments Incorporated 7.3 Feature Description 7.3.1 AnalogInputsandOutputs The PGA2311 includes two independent channels (referred to as the left and right channels). Each channel has a corresponding input and output pin. The input and output pins are unbalanced, or referenced to analog ground (either AGNDR or AGNDL). The inputs are V R (pin 9) and V L (pin 16), and the outputs are V R (pin 11) IN IN OUT andV L(pin14).Theinputandoutputpinscanswingwithin1.25Voftheanalogpowersupplies,V +(pin12) OUT A andV −(pin13).GivenV +=+5VandV −= −5V,themaximuminputoroutputvoltagerangeis7.5Vp-p.

PGA2311 www.ti.com SBOS218D–DECEMBER2001–REVISEDMAY2016 Feature Description (continued) 7.3.2 GainSettings The gain for each channel is set by its corresponding 8-bit code, either R[7:0] or L[7:0] (see Figure 1). The gain code data is straight binary format. If N equals the decimal equivalent of R[7:0] or L[7:0], then the following relationshipsexistforthegainsettings: • ForN=0:MuteCondition.Theinputmultiplexerisconnectedtoanalogground(AGNDRorAGNDL). • ForN=1to255:Gain(dB)=31.5 −[0.5w(255 − N)] Thisresultsinagainrangeof+31.5dB(withN=255)to −95.5dB(withN=1). Changes in gain setting can be made with or without zero-crossing detection. The operation of the zero-crossing detectorandtimeoutcircuitryisdiscussedintheZero-CrossingDetection section. 7.3.3 Daisy-ChainingMultiplePGA2311Devices To reduce the number of control signals required to support multiple PGA2311 devices on a printed circuit board (PCB), the serial control port supports daisy-chaining of multiple PGA2311 devices. Figure 12 shows the connection requirements for daisy-chain operation. This arrangement allows a 3-wire serial interface to control manyPGA2311devices. As shown in Figure 12, the SDO pin from PGA2311 #1 is connected to the SDI input of PGA2311 #2, and is repeated for additional devices. This configuration in turn forms a large shift register, in which gain data can be written for all PGA2311s connected to the serial bus. The length of the shift register is 16 × N bits, where N is equal to the number of PGA2311 devices included in the chain. The CS input must remain LOW for 16 × N SCLKperiods,whereNisthenumberofdevicesconnectedinthechain,toallowenoughSCLKcyclestoloadall devices. Figure12.

PGA2311 SBOS218D–DECEMBER2001–REVISEDMAY2016 www.ti.com Feature Description (continued) 7.3.4 Zero-CrossingDetection The PGA2311 includes a zero-crossing detection function for noise-free level transitions. The concept is to change gain settings on a zero-crossing of the input signal, thus minimizing audible glitches. This function is enabled or disabled using the ZCEN input (pin 1). When ZCEN is LOW, zero-crossing detection is disabled. WhenZCENisHIGH,zero-crossingdetectionisenabled. Thezero-crossingdetectiontakeseffectwithachangeingainsettingforacorrespondingchannel.Thenewgain setting is not implemented until either a positive slope zero crossing is detected, or a time-out period of 16 ms has elapsed. In the case of a time-out, the new gain setting takes effect with no attempt to minimize audible artifacts. 7.3.5 MUTEFunction Muting can be achieved by either hardware or software control. Hardware muting is accomplished through the MUTEinput,andsoftwaremutingbyloadingallzeroesintothevolumecontrolregister. MUTE disconnects the internal buffer amplifiers from the output pins and terminates A L and A R with OUT OUT 10-kΩ resistors to ground. The mute is activated with a zero-crossing detection (independent of the zero-cross enable status), or an 16-ms time-out to eliminate any audible clicks or pops. MUTE also initiates an internal offsetcalibration. A software mute is implemented by loading all zeroes into the volume control register. The internal amplifier is settounitygain,withtheamplifierinputconnectedtoAGND. 7.4 Device Functional Modes 7.4.1 Power-UpState On power-up, power-up reset is activated for approximately 100 ms, during which the circuit is in hardware MUTE state and all internal flip-flops are reset. At the end of this period, the offset calibration is initiated without any external signals. When this step is complete, the gain byte value for both the left and right channels are set to 00 , or the software MUTE condition. The gain remains at this setting until the host controller programs new HEX settingsforeachchannelviatheserialcontrolport. If the power-supply voltage drops below ±3.2 V during normal operation, the circuit enters a hardware MUTE state.Apower-upsequenceinitiatesifthepower-supplyvoltagereturnstogreaterthan ±3.2V. 7.5 Programming The serial control port is used to program the gain settings for the PGA2311. The serial control port includes threeinputpinsandoneoutputpin.TheinputsincludeCS(pin2),SDI(pin3),andSCLK(pin6).Thesoleoutput pinisSDO(pin7). The CS pin functions as the chip-select input. Data can be written to the PGA2311 only when CS is LOW. SDI is the serial data input pin. Control data are provided as a 16-bit word at the SDI pin, 8 bits each for the left and rightchannelgainsettings. Data are formatted as MSB first, in straight binary code. SCLK is the serial clock input. Data are clocked into SDI ontherisingedgeofSCLK. SDO is the serial data output pin, and used when daisy-chaining multiple PGA2311 devices. Daisy-chain operation is described in the Daisy-Chaining Multiple PGA2311 Devices section. SDO is a tri-state output, and assumesahigh-impedancestatewhenCSisHIGH. The protocol for the serial control port is illustrated in Figure 1; see Figure 2 for detailed timing specifications for theserialcontrolport. 12 SubmitDocumentationFeedback Copyright©2001–2016,TexasInstrumentsIncorporated ProductFolderLinks:PGA2311

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. Addendum-Page 1
