# ADS8317IBDGKR

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

ADS8317IBDGKR from Texas Instruments, in a MSOP-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 0.1V to VDD/2. |
| 2 | +IN | input | Noninverting analog input; the full-scale range is +IN minus (-IN), bounded by ±VREF. |
| 3 | -IN | input | Inverting analog input, specified relative to GND within -0.2 V to VDD + 0.2 V. |
| 4 | GND | power_in | Ground reference for the device; all voltage values are with respect to the ground terminal. |
| 5 | CS/SHDN | input | Chip select when low; shutdown mode when high. |
| 6 | DOUT | output | Serial output data word, binary twos complement format. |
| 7 | DCLOCK | input | Data clock that synchronizes the serial data transfer and determines conversion speed, with clock frequency 0.024 to 6.0 MHz. |
| 8 | VDD | power_in | Power supply, 2.7 V to 5.5 V per the recommended operating conditions. |
