The MAX5400/MAX5401 serve well in applications requiring digitally controlled resistors, including adjustable voltage references and programmable gain amplifiers (PGAs). A nominal end-to-end resistor temperature coefficient of 50ppm/C allows these parts to be used as variable resistors in applications such as low-tempco adjustable gain and other circuit configurations. Two resistance values are available: 50k (MAX5400) and 100k (MAX5401). Each device is guaranteed over the extended industrial temperature range (-40C to +85C).
