ADC121C021QIMKX

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

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.
