Dual, 256-Tap, Volatile, Low-Voltage Linear Taper Digital Potentiometer

The MAX5387 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 +2.6V 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 MAX5387 make the device uniquely suitable for the portable consumer market and battery-backup industrial applications.

The MAX5387 is specified over the automotive -40°C to +125°C temperature range and is available in a 14-pin TSSOP package.
