MAX5465EXT+T

Overview

The MAX5465EXT+T is a 32-tap linear-taper digital potentiometer configured as a variable resistor. It features a 50kΩ end-to-end resistance and operates on a single +2.7V to +5.5V supply. The device utilizes a 2-wire serial interface (CS, U/D) for wiper control and includes power-on reset to midscale. Key electrical parameters include an active supply current of 25µA, standby current of 1µA, and glitchless switching between taps. It is housed in a 6-pin SC70 package.

Feature Summary

• Configured as a variable resistor with 50kΩ nominal resistance
• Glitchless switching between 32 tap positions
• Ultra-low supply current: 25µA active, 1µA standby
• Power-on reset sets wiper to midscale

Applications

• LCD screen adjustment
• Volume control
• Mechanical potentiometer replacement
• Gain adjustment
• Line impedance matching

Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging. Confirm the 'EXT' designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this part when a variable resistor configuration is required rather than a potentiometer. The 50kΩ value suits moderate impedance applications. Verify that the 2-wire serial interface timing meets system requirements, specifically the 1MHz toggle rate limit.

Part Context

This component belongs to the MAX5460–MAX5468 FleaPoT family. Unlike the MAX5462/MAX5468 which are configured as potentiometers, the MAX5465 connects the wiper and high terminal internally to function as a two-terminal variable resistor.

Replacement Considerations

Compatible substitutes within the same family include MAX5464EXT+T (variable resistor, 50kΩ, 6-pin SC70) and MAX5463EXK+T (variable resistor, 50kΩ, 5-pin SC70).
