MCP3427T-E

Microchip Tech · Analog To Digital Converters (ADCs) · MSOP-10

MCP3427T-E from Microchip Tech, in a MSOP-10. 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 CH1+ input Positive differential analog input pin of channel 1, with a range of VSS-0.3V to VDD+0.3V.
2 CH1- input Negative differential analog input pin of channel 1, which can be tied to VSS for single-ended operation, with a range of VSS-0.3V to VDD+0.3V.
3 VSS power_in Ground pin and current return path of the device, to be connected to a low-impedance ground plane.
4 CH2+ input Positive differential analog input pin of channel 2, with a range of VSS-0.3V to VDD+0.3V.
5 CH2- input Negative differential analog input pin of channel 2, with a range of VSS-0.3V to VDD+0.3V.
6 VDD power_in Positive supply voltage pin, 2.7V to 5.5V, bypassed with about 0.1 µF ceramic to ground (plus 10 µF tantalum recommended).
7 SDA bidirectional Bidirectional serial data pin of the I2C interface, open-drain N-channel driver needing a pull-up resistor to VDD.
8 SCL input Serial clock pin of the I2C interface (slave only), open-drain N-channel needing a pull-up resistor to VDD.
9 Adr0 input I2C address selection pin (see Section 5.3.2).
10 Adr1 input I2C address selection pin (see Section 5.3.2).
