ADS8689IPWR

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

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.
