Product Summary

The MAX5403EUB+T is a dual 256-tap, low-drift, digital potentiometer in 10μMAX, and it has one 3-terminal potentiometer and one 2-terminal variable resistor. The MAX5403EUB+T operates from +2.7V to +5.5V single-supply voltage and uses an ultra-low supply current of 0.1μA. The MAX5403EUB+T also provides glitchless switching between resistors tap as well as a convenient power-on reset (POR) that sets the wiper to the midscale position at power-up.
