The MAX5478EUD+ 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.
