ADC122S021CIMMX 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 input; conversion initiated on falling edge and continues while CS is held low. |
| 2 | VA | power_in | Positive analog supply voltage (+2.7V to +5.25V) bypassed to GND with 1µF and 0.1µF capacitors within 1cm. |
| 3 | GND | power_in | Ground return for the die. |
| 4 | IN1 | input | Analog input channel 1 with voltage range 0V to VA. |
| 5 | IN2 | input | Analog input channel 2 with voltage range 0V to VA. |
| 6 | DIN | input | Digital data input for control register loading on SCLK rising edges. |
| 7 | DOUT | tri_state | Digital data output (tri-state), clocking out 12-bit conversion results MSB-first on SCLK falling edges. |
| 8 | SCLK | input | Serial clock input (0.8MHz to 3.2MHz range) controlling conversion and readout timing. |
