The MAX5161NEZT-T is a low-power digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It functions as a digitally controlled variable resistor with 32 tap positions, available in a 6-pin SOT-23 package. The device operates on a single supply voltage ranging from +2.7V to +5.5V and consumes only 100nA of supply current. It features linear-taper characteristics with resistance values of 50kΩ, 100kΩ, or 200kΩ. Key performance metrics include ±1LSB differential nonlinearity (DNL) and ±0.5LSB integral nonlinearity (INL). The component is designed for extended industrial temperature ranges from -40°C to +85°C.
This part belongs to the MAX5160/MAX5161 series of linear-taper digital potentiometers. While the MAX5160 utilizes an 8-pin µMAX package, the MAX5161 variant specifically uses a compact 6-pin SOT-23 package. Both devices serve similar functions but differ in pin count and physical footprint, allowing for flexible PCB layout options in space-constrained designs.
The MAX5160LEZT+T is a related component within the same family, offering identical electrical functionality but housed in an 8-pin µMAX package instead of the 6-pin SOT-23. Designers requiring the same performance in a different form factor should consider this alternative.
