MCP3424T-E

Microchip Tech · Analog To Digital Converters (ADCs) · SOIC-14

MCP3424T-E from Microchip Tech, in a SOIC-14. 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 of channel 1; input pins must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage.
2 CH1- input Negative differential analog input of channel 1, which can be tied to VSS for single-ended operation; input pins must stay within VSS-0.3V to VDD+0.3V.
3 CH2+ input Positive differential analog input of channel 2; input pins must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage.
4 CH2- input Negative differential analog input of channel 2, which can be tied to VSS for single-ended operation; input pins must stay within VSS-0.3V to VDD+0.3V.
5 VSS power_in Ground pin and current return path of the device, which must be connected to a ground plane through a low impedance connection.
6 VDD power_in Positive supply pin, which must be maintained in the 2.7V to 5.5V range for specified operation and bypassed with about 0.1 µF ceramic plus 10 µF tantalum capacitors.
7 SDA bidirectional Open-drain N-channel I2C serial data pin that needs a pull-up resistor of 5 kΩ to 10 kΩ for standard and fast modes, or less than 1 kΩ for high speed mode (3.4 MHz).
8 SCL input Open-drain N-channel I2C serial clock pin that accepts only external clocks from the master and needs a pull-up resistor from VDD.
9 Adr0 input I2C address selection pin that is connected to VDD, VSS or left floating to select one of eight available addresses together with Adr1.
10 Adr1 input I2C address selection pin that is connected to VDD, VSS or left floating to select one of eight available addresses together with Adr0.
11 CH3+ input Positive differential analog input of channel 3; input pins must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage.
12 CH3- input Negative differential analog input of channel 3, which can be tied to VSS for single-ended operation; input pins must stay within VSS-0.3V to VDD+0.3V.
13 CH4+ input Positive differential analog input of channel 4; input pins must stay within VSS-0.3V to VDD+0.3V to avoid ESD diode leakage.
14 CH4- input Negative differential analog input of channel 4, which can be tied to VSS for single-ended operation; input pins must stay within VSS-0.3V to VDD+0.3V.
