Microchip MCP4561T-503E/MF 50kΩ Single-Channel Digital Potentiometer Overview
The Microchip MCP4561T-503E/MF is a highly integrated single-channel digital potentiometer designed to provide a digitally controlled variable resistor solution. With a nominal resistance of 50kΩ, this device serves as a robust alternative to traditional mechanical potentiometers, offering enhanced precision, reliability, and programmability in a compact package. It is part of Microchip’s extensive family of non-volatile memory (NVM) digital POTs, making it suitable for a wide range of analog signal processing and adjustment applications.
This IC operates with a 7-bit resolution, providing 128 wiper positions that allow for fine-grained adjustment of resistance. The MCP4561T-503E/MF features an SPI-compatible serial interface, enabling simple and efficient communication with microcontrollers or digital processors. Its ability to retain wiper settings during power-off—thanks to integrated EEPROM—ensures consistent performance upon power-up, which is critical for applications requiring preset configurations.
Housed in a small-form-factor DFN package, the device is ideal for space-constrained designs such as portable electronics, sensor calibration circuits, audio equipment, and programmable power supplies. It supports a wide voltage range and low power consumption, making it suitable for both battery-powered and line-operated systems.
Key advantages include excellent temperature stability, low wiper resistance, and high endurance of EEPROM write cycles. These attributes make the MCP4561T-503E/MF a versatile component for system tuning, volume control, feedback loop adjustment, and other applications where digital control of resistance values improves performance and usability.
