ADC121C021QIMK

Texas Instruments · Analog To Digital Converters (ADCs) · TSOT-23-6

ADC121C021QIMK 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 that must be free of noise and decoupled to GND, operating 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 Open-drain alert output that can be configured as active high or active low and must be pulled up to VA with an external resistor.
5 SCL input I2C serial clock input used together with SDA to control data transfer, an open-drain line that must be pulled up to VA with an external resistor.
6 SDA bidirectional I2C serial data bi-directional connection clocked into or out of the internal 16-bit register with SCL, an open-drain line that must be pulled up to VA with an external resistor.
