Description

The MAX5392 dual, 256-tap, volatile, low-voltage, linear taper digital potentiometer offers three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Operating from a single +1.7V to +5.5V power supply, the device provides a low, 35ppm/°C end-to-end temperature coefficient. The device features an I²C interface.

The small package size, low supply operating voltage, low supply current, and automotive temperature range of the MAX5392 makes the device uniquely suited for the portable consumer market, battery-backup industrial applications, and the automotive market.

The MAX5392 is specified over the automotive -40°C to +125°C temperature range and is available in a 16-pin TSSOP package.
