ADC122S021CIMM from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; 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 conversions continue as long as CS is held low. |
| 2 | VA | power_in | Positive supply pin, to be connected to a quiet +2.7V to +5.25V source and bypassed to GND with a 1 µF and a 0.1 µF capacitor located within 1 cm of the pin. |
| 3 | GND | power_in | Ground return for the die. |
| 4 | IN2 | passive | Analog input channel 2; signal can range from 0V to VA. |
| 5 | IN1 | passive | Analog input channel 1; signal can range from 0V to VA. |
| 6 | DIN | input | Digital data input; the Control Register is loaded through this pin on rising edges of SCLK. |
| 7 | DOUT | tri_state | Digital data output; conversion result samples are clocked out of this pin on falling edges of SCLK, and the pin is high-impedance when CS is high. |
| 8 | SCLK | input | Digital clock input that directly controls the conversion and readout processes. |
