MAX5462EXT+T

Overview

The MAX5462EXT+T is a 32-tap digital potentiometer from the FleaPoT family, configured as a variable resistor with a nominal end-to-end resistance of 100kΩ. It operates on a single supply voltage ranging from +2.7V to +5.5V and draws an active supply current of 25µA. The device features a 2-wire serial interface for wiper control, glitchless switching between taps, and a power-on reset that initializes the wiper to midscale. It is housed in a space-saving 6-pin SC70 package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• 32-tap resolution with 100kΩ nominal resistance
• Ultra-low supply current: 25µA active, 0.3µA standby
• Glitchless switching between resistor taps
• Power-on reset to midscale position

Applications

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

Procurement Notes

Verify the component against the official Analog Devices / Maxim Integrated datasheet (19-1956; Rev 3) to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required package type and tape-and-reel configuration for automated assembly processes.

Selection Notes

Select this part when a digitally controlled 100kΩ variable resistor is required in a compact footprint. The 6-pin SC70 package is suitable for space-constrained designs. Consider the 2-wire serial interface timing requirements and ensure the system voltage falls within the 2.7V to 5.5V operational range.

Part Context

This component belongs to the MAX5460–MAX5468 series of 32-tap digital potentiometers. While other devices in the family offer 10kΩ or 50kΩ resistance values, the MAX5462 specifically provides the 100kΩ option in a 6-pin SC70 package, distinguishing it from the 5-pin variants and lower-resistance counterparts.

Replacement Considerations

Direct replacements within the same family include the MAX5461EXT (variable resistor, 100kΩ, 6-pin SC70). For different resistance values, consider the MAX5464EXT (50kΩ) or MAX5467EUT (10kΩ), noting differences in package style and terminal configuration.
