ADS8691IPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); 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. 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. Decouple with the AIN_GND pin. |
| 8 | AIN_GND | input | Analog input: negative. 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. Active high logic: conversion start input pin; a CONVST rising edge brings the device from acquisition phase to conversion phase. Active low logic: chip-select input pin; the device takes control of the data bus when CS is low; the 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. |
| 14 | ALARM/SDO-1/GPO | output | Multi-function output pin. Active high alarm. Data output 1 for serial communication. General-purpose output pin. |
| 15 | RVS | output | Multi-function output pin for serial interface; see the RESET State section. 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. |
