MCP3425A2T-E

Microchip Tech · Analog To Digital Converters (ADCs) · SOT-23-6

MCP3425A2T-E from Microchip Tech, in a SOT-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 VIN+ power_in Positive differential analog input pin; absolute voltage range is VSS-0.3V to VDD+0.3V and differential input should not exceed VREF/PGA.
2 VSS power_in Ground pin and current return path of the device, to be connected to a ground plane (analog ground if available) through a low impedance connection.
3 SCL input Serial clock input of the I2C interface (slave only, open-drain N-channel driver) that needs a pull-up resistor from VDD.
4 SDA bidirectional Bidirectional serial data pin of the I2C interface (open-drain N-channel driver) that needs a pull-up resistor from VDD.
5 VDD power_in Positive supply pin, 2.7V to 5.5V for specified operation, with about 0.1 µF ceramic bypass to ground and an additional 10 µF tantalum recommended.
6 VIN- power_in Negative differential analog input pin; absolute voltage range is VSS-0.3V to VDD+0.3V and differential input should not exceed VREF/PGA.
