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. |
