MCP4822E-SN - Brand New MIC Digital To Analog Converters (DACs)
-
Description
The MCP4822E-SN is a 7-bit single I²C™ digital potentiometer with volatile memory. It is categorized as a Digital to Analog Converter (DAC) and is available in the SC70 package. The device offers potentiometer or rheostat configuration options and has a resolution of 7 bits, with 128 steps or 127 resistors. The MCP4822E-SN has a wide operating voltage range of 2.7V to 5.5V and can be operated in an extended temperature range of -40°C to +125°C. It is designed for low-power operation, with a static current of 2.5 µA. The device also features a simple I2C protocol with read and write commands, as well as other characteristics such as low wiper resistance, low temperature coefficient, and power-on default wiper setting.
