Maxim Integrated MAX5402
The MAX5402 µPoT™ digital potentiometer is a 256-tap variable resistor with 10kΩ total resistance in a tiny 8pin µMAX package. This device functions as a mechanical 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 0.1µA supply current.- Min Voltage : 2.7V
- Max Voltage : 5.5V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C

GENERAL DESCRIPTION
This device also provides 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/°C ratiometric temperature coefficient makes it ideal for applications requiring low drift. The MAX5402 serves 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 35ppm/°C makes this part suitable for use as a variable resistor in applications such as low-tempco adjustable gain and other circuit configurations. This device is guaranteed over the extended industrial temperature range (-40°C to +85°C). o Ultra-Low 100nA Supply Current o +2.7V to +5.5V Single-Supply Operation o 256 Tap Positions o Low Ratiometric Temperature Coefficient 5ppm/°C o Low End-to-End Resistor Temperature Coefficient 35ppm/°C o Power-On Reset: Wiper Goes to Midscale...
