ADC122S051QIMM 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 falling edge on CS starts a conversion, and conversions continue as long as CS is held low. |
| 2 | VA | power_in | Positive supply, to be connected to a quiet +2.7V to +5.25V source and 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 channel 2, which can range from 0V to VA. |
| 5 | IN1 | input | Analog input channel 1, which can range from 0V 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 −0.3V to VA. |
| 7 | DOUT | output | Digital data output, with samples clocked out on falling edges of the SCLK pin. |
| 8 | SCLK | input | Digital clock input that directly controls the conversion and readout processes; clock frequency range is 50 kHz to 16 MHz. |
