MCP45HV31T-503E/MQ

Digital potentiometers, also known as programmable resistor, are widely used in various industrial, commercial and consumer applications. The MCP45HV31T-503E/MQ is a 16-bit digital potentiometer with a fast 8-bit up/down serial interface. With this device, users can easily implement assemblies for digital voltage dividers and digital-controlled amplifiers.

Application Fields

The MCP45HV31T-503E/MQ is well suited for a variety of applications such as programmable voltage and current dividers, digitally controlled amplifiers and adjustable output power supplies. Its 16-bit resolution offers a much finer resolution than a traditional potentiometer and its 8-bit serial interface can provide fast control of the output. It can also be used in voltage regulation circuits, motor control circuits, and applications where you need to set a precise resistance or voltage.

Working Principle

The working principle of the MCP45HV31T-503E/MQ is based on its core technology, which is a memory array of resistive elements. When a voltage is applied across the wiper and one of the terminals, the resistance between them is calculated by the amount of current flowing through the array proportional to the applied voltage.

This device uses an internal 8-bit shift register to store and control the wiper position. The devices feature an EEPROM memory array, which is used to store the set point for the wiper position. The User can also adjust the resistance value by sending a serial command to the device.

Once the external voltage is applied, the digital potentiometer can be used to make adjustments to the device\'s performance. The device will then monitor the output and adjust accordingly to the desired resistance set by the user.

The MCP45HV31T-503E/MQ is a versatile and cost-effective way to implement various digital potentiometer applications.
