The MAX5400EKA+T is a 256-tap digital potentiometer from Analog Devices, designed as a SOT-PoT™ digitally controlled variable resistor. It functions like a mechanical potentiometer with a fixed resistor string and a digitally controlled wiper contact.
This device operates from a single supply voltage range of +2.7V to +5.5V and consumes an ultra-low supply current of 0.1µA. It features glitchless switching between resistor taps and a power-on reset function that sets the wiper to the midscale position. The low ratiometric temperature coefficient of 5ppm/°C and an end-to-end resistance temperature coefficient of 50ppm/°C make it suitable for applications requiring low drift.
Available with a resistance value of 50k Ohm, the MAX5400EKA+T is guaranteed for operation over the extended industrial temperature range of -40°C to +85°C. It is housed in a miniature 8-pin SOT-23 package, making it ideal for space-constrained designs. The 3-wire SPI-compatible interface simplifies integration into digital control systems.
Applications include mechanical potentiometer replacement, low-drift programmable gain amplifiers (PGAs), and adjustable voltage references. Its features make it a versatile component for various electronic circuits requiring digitally controlled resistance.
