# ADS8326IDGKR

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

ADS8326IDGKR 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 voltage analog input; must be between 0.1V and VDD. |
| 2 | +IN | input | Noninverting analog input; differential range 0 to VREF with respect to -IN. |
| 3 | -IN | input | Inverting analog input; referenced to ground with operating common-mode signal from -0.3V to 0.5V. |
| 4 | GND | power_in | Ground connection serving as 0V reference. |
| 5 | CS/SHDN | input | Digital chip select / shutdown control; active low for normal operation, high for power-down mode. |
| 6 | DOUT | tri_state | Serial digital output with three-state control; MSB-first 16-bit data format followed by zeros when CS remains low. |
| 7 | DCLOCK | input | Digital clock input synchronizing serial data transfer; frequency range 0.024 MHz to 6 MHz. |
| 8 | VDD | power_in | Power supply input; operating voltage range 2.7V to 5.5V. |
