Maxim Integrated MAX5400

The MAX5400/MAX5401 digital potentiometers offer 256-tap SOT-PoT™ digitally controlled variable resistors in tiny 8-pin SOT23 packages. Each device functions as a mechanical potentiometer, consisting of a fixed resistor string with a digitally controlled wiper contact. They operate from +2.7V to +5.5V single-supply voltages and use an ultra-low supply current of 0.1µA.

GENERAL DESCRIPTION

These devices also provide glitchless switching between resistor taps, as well as a convenient poweron reset that sets the wiper to the midscale position at power-up. A low 5ppm/°C ratiometric temperature coefficient makes it ideal for applications requiring low drift. 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: 50kΩ (MAX5400) and 100kΩ (MAX5401). Each device is guaranteed over the extended industrial temperature range (-40°C to +85°C). o Miniature 8-Pin SOT23 (3mm x 3mm) o 256 Tap Positions o Ultra-Low 0.1µA Supply Current o Single-Supply Operation: +2.7V to +5.5V o Low Ratiometric Temperature Coefficient:...
