ADC101C021CIMM from Texas Instruments, in a VSSOP-8-0.65mm. 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 | SCL | input | I2C serial clock input with open-drain line requiring external pull-up to VA and 8kV HBM ESD protection. |
| 2 | ALERT | tri_state | Configurable active-high or active-low alert output with open-drain output requiring external pull-up to VA. |
| 3 | ADR0 | input | Tri-level address selection input that configures Bits A0 & A1 of the 7-bit slave address. |
| 4 | VIN | power_in | Analog input ranging from GND to VA. |
| 5 | VA | power_in | Supply voltage and reference input that must be free of noise and decoupled to GND. |
| 6 | ADR1 | input | Tri-level address selection input that configures Bits A2 & A3 of the 7-bit slave address. |
| 7 | GND | power_in | Ground for all on-chip circuitry. |
| 8 | SDA | bidirectional | I2C serial data bidirectional line with open-drain output, external pull-up to VA, and 8kV HBM ESD protection. |
