The MAX5479EUD+ is a dual non-volatile linear taper digital potentiometer in 14 pin TSSOP package. This device combines two independently controlled 256 position potentiometers and the device control is achieved through I2C interface. The low temperature coefficient makes the device ideal for applications requiring a low temperature coefficient variable resistor such as low drift, programmable gain amplifier circuit configurations.
