Overview

The MAX5402EUA uPoTW digital potentiometer is a 256-tap variable resistor with 10k2 total resistance in a tiny 8-pin uMAX package. This device functions as a mechan-ical potentiometer, consisting of a fixed resistor string with a digitally controlled wiper contact. It operates from+2.7V to +5.5V single-supply voltages and uses an ultra-low 0.1uA supply current. This device also pro-vides glitchless switching between resistor taps, as well as a convenient power-on reset(POR) that sets the wiper to the midscale position at power-up.A low 5ppm/PC ratiometric temperature coefficient makes it ideal for applications requiring low drift. The MAX5402EUA serves well in applications requiring digi-tally controlled resistors, including adjustable voltage references and programmable gain amplifiers (PGAs). A nominal end-to-end resistor temperature coefficient of 35ppm/C makes this part suitable for use as a variableresistor in applications such as low-tempco adjustable gain and other circuit configurations. This device is guaranteed over the extended industrial temperature range(-40℃ to+85℃).
