MAX5161MEZT+T

The MAX5161MEZT+T is a low-power digital potentiometer in 6 pin SOT23 package. It is a linear-taper digital potentiometer that performs the same function as a mechanical potentiometer or a variable resistor. It consists of a fixed resistor and a wiper contact with 32 tap points that are digitally controlled by two lines for the 6-pin MAX5161. It is an ideal for applications requiring digitally controlled resistors. A nominal resistor temperature coefficient of 50ppm/°C end-to-end and only 5ppm/°C ratiometric makes the MAX5161 ideal for applications requiring a low-temperature- coefficient variable resistor, such as low-tempco, adjustable-gain circuit configurations. Typical applications include LCD screen adjustment, volume control and mechanical potentiometer replacement.
