# ADS8317IBDGKT

**Texas Instruments** · Analog To Digital Converters (ADC) · VSSOP-8

ADS8317IBDGKT from Texas Instruments, in a VSSOP-8. 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 | REF | input | Reference input; the reference voltage can be set to any level within the range of 0.1 V to VDD/2. |
| 2 | +IN | input | Noninverting analog input; the absolute input range is -0.1 V to VDD + 0.1 V. |
| 3 | -IN | input | Inverting analog input; the recommended voltage range to GND is -0.2 V to VDD + 0.2 V. |
| 4 | GND | power_in | Ground, the power-supply connection for the device. |
| 5 | CS/SHDN | input | Chip select when low; shutdown mode when high. |
| 6 | DOUT | output | Serial output data word. |
| 7 | DCLOCK | input | Data clock that synchronizes the serial data transfer and determines conversion speed, with a clock frequency of 0.024 MHz to 6.0 MHz. |
| 8 | VDD | power_in | Power supply; 2.7 V to 5.5 V (4.5 V to 5.5 V for 5 V logic levels). |
