# ADS8319IDGST

**Texas Instruments** · Analog To Digital Converters (ADC) · VSSOP-10-0.5mm

ADS8319IDGST from Texas Instruments, in a VSSOP-10-0.5mm. 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 | REFIN | input | Reference (positive) input; decouple to GND with 0.1-µF bypass capacitor and 10-µF storage capacitor. |
| 2 | +VA | power_in | Analog power supply voltage input; decouple to GND. |
| 3 | +IN | input | Noninverting analog signal input. |
| 4 | -IN | input | Inverting analog signal input limited to ±0.1 V, typically grounded at input decoupling capacitor. |
| 5 | GND | power_in | Device ground for analog power supply (+VA) and digital I/O supply (+VBD). |
| 6 | CONVST | input | Conversion start input; also functions as CS input in 3-wire interface mode. |
| 7 | SDO | output | Serial data output. |
| 8 | SCLK | input | Serial I/O clock input; data on SDO output are synchronized with this clock. |
| 9 | SDI | input | Serial data input; level at conversion start selects mode of operation (CS or daisy-chain); also CS input in 4-wire interface mode. |
| 10 | +VBD | power_in | Digital I/O power supply voltage input; decouple to GND. |
