The MCP4021-202E/SN is an Integrated Circuit (IC) component designed and manufactured by Microchip Technology Inc. It is a dual digital potentiometer with EEPROM (Electrically Erasable Programmable Read-Only Memory). The MCP4021-202E/SN offers high accuracy, low power consumption, and digital interface control, making it an ideal choice for various applications.
Key features of the MCP4021-202E/SN include:
1. Dual Digital Potentiometer: The IC incorporates two digitally controlled potentiometers that allow users to adjust resistance through a digital interface. This feature enables precise and convenient control over the circuit's resistance.
2. Non-Volatile EEPROM Memory: The IC includes non-volatile EEPROM memory, allowing the device to retain its settings even when power is removed. This feature is advantageous in applications where persistence of previous settings is required.
3. Wide Resistance Range: The MCP4021-202E/SN provides a wide resistance range, making it suitable for a variety of applications. It offers a total resistance range of 5 kiloohms (kΩ) to 100 kiloohms (kΩ), which can be divided among the two potentiometers as required.
4. High Resolution: With its 7-bit resolution, the MCP4021-202E/SN offers 128 tap points for each potentiometer. This high resolution allows for precise adjustment and fine-tuning of the resistance value
