MAX5450, MAX5451, MAX5452, MAX5453, MAX5454, MAX5455 Dual, 256-Tap, Up/Down Interface, Digital Potentiometers

Description

The MAX5450—MAX5455 are a family of dual digital potentiometers that perform the same function as a mechanical potentiometer or variable resistor. The MAX5451/MAX5453/MAX5455 have two 3-terminal potentiometers and the MAX5450/MAX5452/MAX5454 have two 2-terminal variable resistors. The MAX5450—MAX5455 operate from a +2.7V to +5.5V single-supply voltage and use an ultra-low supply current of 0.1µA. These devices consist of two fixed resistors each with 256 digitally-controlled wiper contacts. The convenient power-on reset (POR) sets the wiper to midscale position at power-up and the easy-to-use up/down interface allows glitchless switching between resistor taps. Six inputs control the 14-pin MAX5451/MAX5453/MAX5455 potentiometers. Four inputs control the 10-pin MAX5450/MAX5452/MAX5454 variable resistors.

The MAX5450—MAX5455 are ideal for applications requiring digitally-controlled resistors. Three resistance values are available: 10kΩ, 50kΩ, and 100kΩ. An end-to-end resistor temperature coefficient of 35ppm/°C and a ratiometric temperature coefficient of 5ppm/°C make the MAX5450—MAX5455 excellent choices for adjustable gain circuit requiring low-temperature drift.

The MAX5450—MAX5455 are available in 10-pin µMAX® and 14-pin TSSOP packages. Each device is guaranteed over the extended—industrial temperature range (-40°C to +85°C).
