The MCP4161T-503E/SN is an IC component that belongs to the MCP416x series of digital potentiometers manufactured by Microchip Technology. It is a low-cost, non-volatile, 50kΩ digital potentiometer with 256 taps offering a wide range of applications in various industries.
One of the key features of the MCP4161T-503E/SN is its ability to digitally control resistance, replacing traditional mechanical potentiometers. This digital control is advantageous as it enables remote and automated adjustments with high accuracy and resolution.
The MCP4161T-503E/SN operates from a single power supply, ranging from 2.7V to 5.5V, making it suitable for low-power designs. It also has low power consumption, with typical active current of 4µA and a standby current of 1µA. This makes it an efficient choice for applications sensitive to power consumption, such as battery-powered devices.
The device communicates through a 3-wire SPI interface, allowing for easy integration with microcontrollers or other digital systems. It supports daisy-chaining, meaning multiple pots can be connected in series on the same bus to minimize the number of data lines required.
Another notable feature is its non-volatile memory, which ensures that the resistance settings are retained even when the power is turned off. This eliminates the need for re-calibration and enhances system reliability
