ADS8685IPWR

Texas Instruments · Analog To Digital Converters (ADC) · TSSOP-16

ADS8685IPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DGND power_in Digital ground pin; decouple with the DVDD pin.
2 AVDD power_in Analog supply pin; decouple with the AGND pin.
3 AGND power_in Analog ground pin; decouple with the AVDD pin.
4 REFIO bidirectional Internal reference output and external reference input pin; decouple with REFGND.
5 REFGND power_in Reference ground pin; short to the analog ground plane and decouple with the REFIO and REFCAP pins.
6 REFCAP output ADC reference buffer decoupling capacitor pin; decouple with the REFGND pin.
7 AIN_P input Analog input positive pin; decouple with the AIN_GND pin.
8 AIN_GND input Analog input negative pin; decouple with the AIN_P pin.
9 RST input Active low logic input to reset the device.
10 SDI input Dual function data input pin for serial communication; chain data input during serial communication in daisy-chain mode.
11 CONVST/CS input Dual-functionality pin acting as active high conversion start input or active low chip-select input; device takes control of data bus when CS is low and SDO-x pins go to tri-state when CS is high.
12 SCLK input Serial communication clock input pin for the serial interface; all system-synchronous data transfer protocols are timed with respect to the SCLK signal.
13 SDO-0 output Serial communication data output 0 pin.
14 ALARM/SDO-1/GPO output Multifunction output pin for active high alarm, data output 1 for serial communication, or general-purpose output.
15 RVS output Multifunction output pin for serial interface; with CS held high, RVS reflects the status of the internal ADCST signal; with CS low, the status of RVS depends on the output protocol selection.
16 DVDD power_in Digital supply pin; decouple with the DGND pin.
