MCP4652-104E/UN

Data acquisition is an important process in many industries, and accurate results of the data acquired can be crucial to the success of any project. The precise control of analog signals is a key part of this process, and digital potentiometers are an effective way to achieve this. One such digital potentiometer is the MCP4652-104E/UN.

The MCP4652-104E/UN is manufactured by Microchip Technology and is a member of the MCP4652 family of products. It is a 10-bit digital potentiometer with non-volatile memory and I2C interface controls. This device is ideal for applications where precise control of analog signals is required and is available in a 10-pin SOIC package with a 0.100” pitch spacing.

The device has an up/down resistive-ladder network and I2C interface controls. This allows the user to accurately control the output voltage of the device using the onboard EEPROM memory for storing the desired value. When the device is powered-up, it loads the stored value directly into the on-board RAM, thus eliminating the need to read and write the EEPROM during normal operations. The device also has an internal EEPROM redundancy feature that allows the device to verify and recover from programming errors made while programming the EEPROM.

The MCP4652-104E/UN is ideal for applications such as digital volume control, gain control, and trimming applications. This device provides the user with 10-bit resolution and a total span of resistance up to 3.2 kilo-ohms. Additionally, it has a low power consumption of 2.4 mA at 5.0V operating voltage. This makes the device suitable for low-power applications.

The device’s working principle is straightforward and is based on the use of a resistive-ladder network connected to I2C interface controls. These controls allow the user to adjust the resistance value of the device by sending data via the I2C interface. Data is first loaded into the on-board RAM, and then the device adjusts the resistive ladder network to match the requested output voltage. This device also has an on-board EEPROM which stores the desired output value, and this value is automatically loaded into the RAM upon power on.

The MCP4652-104E/UN digital potentiometer is an effective and reliable method of controlling analog signals. Its 10-bit resolution, up to 3.2 kilo-ohm total span, and low power consumption make it the ideal choice for applications such as digital volume control, gain control, and trimming applications. Its straightforward working principle and on-board EEPROM make it an easy-to-use and reliable device for any application.
