MAX5456EEE+T

Overview

The MAX5456EEE+T is a dual digital potentiometer IC from Analog Devices, packaged in a QSOP-16. It features two independent 32-tap wiper positions with a logarithmic taper, designed for stereo audio applications. The device operates on a supply voltage ranging from 2.7V to 5.5V and draws a typical operating current of 100µA. It utilizes a debounced pushbutton interface for direct control without external logic. The unit supports surface-mount installation and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual channel configuration with 32 taps per potentiometer
• Logarithmic taper suitable for audio volume control
• Debounced pushbutton up/down interface
• Low power consumption with 100µA operating current

Applications

• Stereo audio volume control circuits
• Gain adjustment in analog signal paths
• Consumer electronics requiring manual level adjustment

Procurement Notes

Verify the specific suffix EEE+T against the manufacturer's datasheet to confirm the reel packaging quantity and RoHS compliance status. Ensure the QSOP-16 footprint matches the PCB design requirements before ordering. Check for any regional distribution restrictions that may affect availability.

Selection Notes

Select this component when a dual-channel solution with logarithmic response is required for audio applications. The debounced pushbutton interface simplifies hardware design by eliminating the need for microcontroller-based SPI or I2C communication. Verify that the 10kΩ resistance value meets the circuit impedance requirements.

Part Context

This part belongs to the MAX5456 series of digital potentiometers. It is distinct from linear taper variants like the MAX5455 and offers a specialized logarithmic curve optimized for human hearing perception in audio systems. The QSOP-16 package provides a compact form factor for space-constrained designs.

Replacement Considerations

For linear taper requirements, consider the MAX5455EUD+. For different resistance values or tap counts, review other members of the MAX54xx family. Ensure any substitute maintains the same QSOP-16 package and voltage specifications.
