MAX5400：256抽头SOT-PoT、低漂移数字电位器，SOT23封装
256抽头数字电位器，提供节省空间的8引脚SOT23封装
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. These devices also provide glitchless switching between resistor taps, as well as a convenient power-on 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).
