The MCP4461T-503E/ML is a digitally-controlled (I2C interface) potentiometer, manufactured by Microchip Technology. This device is part of the MCP4461 series, which offers a versatile solution for applications requiring digitally controlled resistors. The MCP4461T-503E/ML features a quad-channel configuration, providing multiple resistors in a single package for enhanced design flexibility.

With a resistance value of 50kΩ and a tolerance of ±20%, this digital potentiometer is designed for an array of applications, including calibration and tuning functions within electronic circuits. The device operates over a wide voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems and ensuring compatibility with various microcontroller logic levels.

The MCP4461T-503E/ML comes in a compact, 14-lead QFN (ML) package, which is ideal for space-constrained applications. Its non-volatile memory (EEPROM) allows the potentiometer to retain the wiper position upon power-down, ensuring consistent performance and reducing the need for recalibration at power-up. This feature is particularly useful in applications that require precise and repeatable adjustments.

This digital potentiometer also includes an array of internal features that enhance its performance and reliability. These features include wiper lock technology to prevent inadvertent wiper movement and brown-out reset, which ensures that the device returns to a known state after a power interruption. Additionally, the MCP4461T-503E/ML supports both volatile and non-volatile wiper operations, giving designers the flexibility to choose between temporary or permanent adjustments.

The MCP4461T-503E/ML is an excellent choice for designers looking to integrate digital potentiometer functionality into their applications, such as adjustable power supplies, LCD screen calibration, audio control, and industrial automation systems. Its robust feature set, combined with Microchip's reputation for quality and support, makes it a reliable and cost-effective solution for precision control needs.
