ADC121C021QIMKX from Texas Instruments, in a TSOT-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 | Power supply and unbuffered reference voltage; VA must be free of supply noise and decoupled to GND, and the part operates from +2.7V to +5.5V. |
| 2 | GND | power_in | Ground for all on-chip circuitry. |
| 3 | VIN | power_in | Analog input that can range from GND to VA. |
| 4 | ALERT | output | Alert output that can be configured as active high or active low; it is an open-drain line that must be pulled up to VA with an external pull-up resistor. |
| 5 | SCL | input | Serial clock input used with SDA to control data transfer in and out of the device; it is an open-drain line that must be pulled up to VA with an external pull-up resistor. |
| 6 | SDA | bidirectional | Serial data bidirectional connection; data is clocked into or out of the internal 16-bit register with SCL, and it is an open-drain line that must be pulled up to VA with an external pull-up resistor. |
