ADS8689IPWR 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 DVDD pin. |
| 2 | AVDD | power_in | Analog supply voltage pin (4.75 to 5.25 V); decouple with AGND pin. |
| 3 | AGND | power_in | Analog ground pin; decouple with AVDD pin. |
| 4 | REFIO | bidirectional | Internal 4.096-V reference output or external reference input pin; decouple with REFGND. |
| 5 | REFGND | power_in | Reference ground pin; short to analog ground plane; decouple with REFIO and REFCAP pins. |
| 6 | REFCAP | passive | Reference buffer decoupling capacitor pin; decouple with REFGND (10 µF minimum). |
| 7 | AIN_P | input | Analog input positive; input impedance ≥ 1 MΩ; operating range ±12.288 V to ±2.56 V (bipolar) or 0 to 12.288 V (unipolar). |
| 8 | AIN_GND | input | Analog input negative reference; operating range ±0.1 V; decouple with AIN_P pin. |
| 9 | RST | input | Active low asynchronous reset input; minimum pulse width 100 ns; rising edge brings device from RESET to ACQ state. |
| 10 | SDI | input | Serial data input for multiSPI communication; dual function as chain data input during daisy-chain mode. |
| 11 | CONVST/CS | input | Dual-function input; active high rising edge initiates conversion, active low enables chip select; maximum frequency 66.67 MHz. |
| 12 | SCLK | input | Serial clock input for multiSPI interface; maximum frequency 66.67 MHz; times all system-synchronous data transfer protocols. |
| 13 | SDO-0 | tri_state | Serial data output 0 (primary data output); tri-states when CONVST/CS is high (transition time 10 ns max). |
| 14 | ALARM/SDO-1/GPO | tri_state | Multifunction tri-state output; configurable as active high alarm, serial data output 1, or general-purpose output; tri-states when CONVST/CS is high. |
| 15 | RVS | output | Multifunction output pin for serial interface; reflects internal ADCST signal with CS high or output protocol status with CS low; indicates conversion completion. |
| 16 | DVDD | power_in | Digital supply voltage pin (1.65 to AVDD V; specified performance 2.7 to AVDD V); decouple with DGND pin. |
