ADC121S021CIMFX from Texas Instruments, in a SOT-23-6. 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 | VA | power_in | Positive supply pin connected to a quiet 2.7-V to 5.25-V 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. |
| 2 | GND | power_in | The ground return for the supply and signals. |
| 3 | VIN | power_in | Analog input signal that can range from 0 V to VA. |
| 4 | SCLK | input | Digital clock input that directly controls the conversion and readout processes. |
| 5 | SDATA | output | Digital data output with samples clocked out on falling edges of the SCLK pin. |
| 6 | CS | input | Chip select; conversion process begins on the falling edge of CS. |
