MCP3021A5T-E from Microchip Tech, in a SOT-23-5. 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 pin for I2C bus synchronization; open-drain capable; voltage range VSS to VDD+1.0V. |
| 2 | AIN | input | Single-ended analog input to SAR converter sample-and-hold circuit; input voltage range VSS-0.3V to VDD+0.3V; input leakage current ±1 µA maximum. |
| 3 | VSS | power_in | Ground and negative supply reference terminal for all circuit functions. |
| 4 | VDD | power_in | Positive power supply pin; operating voltage range 2.7V to 5.5V; provides reference voltage for A/D conversions. |
| 5 | SDA | bidirectional | Bidirectional serial data pin for I2C bus; open-drain capable; voltage range VSS to VDD+1.0V; enables address and data transmission. |
