# ADC102S021CIMM

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

ADC102S021CIMM 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 | CS | input | Chip select: a conversion process begins on the falling edge of CS and continues as long as CS is held low. |
| 2 | VA | power_in | Positive supply pin, specified for +2.7 V to +5.25 V, to be bypassed to GND with a 1 µF capacitor and a 0.1 µF monolithic capacitor located within 1 cm of the power pin. |
| 3 | GND | power_in | Ground return for the die. |
| 4 | IN2 | input | Analog input that can range from 0 V to VA. |
| 5 | IN1 | input | Analog input that can range from 0 V to VA. |
| 6 | DIN | input | Digital data input through which the Control Register is loaded on rising edges of SCLK; digital input voltage range is −0.3 V to VA. |
| 7 | DOUT | output | Digital data output; output samples are clocked out of this pin on falling edges of SCLK. |
| 8 | SCLK | input | Digital clock input that directly controls the conversion and readout processes. |
