**Texas Instruments** · Analog To Digital Converters (ADCs) · VSSOP-8-0.65mm

ADC081C021CIMM 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 | Serial Clock Input for I2C interface control; open-drain line requiring external pull-up to VA; extended ESD tolerance of 8 kV HBM. |
| 2 | ALERT | tri_state | Alert output indicating out-of-range condition; open-drain line requiring external pull-up to VA; configurable as active high or active low. |
| 3 | ADR0 | input | Tri-level Address Selection Input setting bits A0 and A1 of the 7-bit I2C slave address; can be grounded, floating, or tied to VA. |
| 4 | VIN | power_in | Analog input signal; voltage range from 0 V to VA. |
| 5 | VA | power_in | Positive supply voltage and unbuffered reference; operating range +2.7 V to +5.5 V; must be decoupled to GND with bypass capacitors and kept free of noise. |
| 6 | ADR1 | input | Tri-level Address Selection Input setting bits A2 and A3 of the 7-bit I2C slave address; can be grounded, floating, or tied to VA. |
| 7 | GND | power_in | Ground reference for all on-chip circuitry. |
| 8 | SDA | bidirectional | Serial Data bi-directional connection for I2C interface; open-drain line requiring external pull-up to VA; extended ESD tolerance of 8 kV HBM. |
