The MAX5389MAUD+T is a dual, 256-tap, volatile, low-voltage linear taper digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features an end-to-end resistance of 50kΩ and operates from a single +2.6V to +5.5V power supply. The device provides a low 35ppm/°C temperature coefficient and consumes less than 1μA of quiescent supply current. It utilizes an up/down interface for wiper control and sets the wiper to midscale upon power-on. The component is specified over an extended operating temperature range of -40°C to +125°C and is housed in a 14-pin TSSOP package.
Verify that the specific part number corresponds to the 50kΩ variant within the MAX5389 family. Confirm RoHS compliance status based on the '+' suffix designation. Ensure the application environment remains within the specified -40°C to +125°C automotive temperature range. Check for any required external bypass capacitors near the VDD pin as recommended in the datasheet.
Select this component when a dual-channel digital potentiometer with a 50kΩ resistance value is required. The volatile memory type necessitates re-initialization after power cycles, though the device defaults to midscale. Consider the up/down interface requirements versus serial interfaces available in other variants. Verify that the continuous current limits for the 50kΩ version (±2mA) meet the circuit load requirements.
This component belongs to the MAX5389 series of dual digital potentiometers. Other variants in the series include the MAX5389LAUD+T with 10kΩ resistance and the MAX5389NAUD+T with 100kΩ resistance. All share the same 14-pin TSSOP package, 256-tap resolution, and up/down interface functionality while differing primarily in their end-to-end resistance values.
