MAX5410EEE+T

Overview

The MAX5410EEE+T is a dual, logarithmic taper digital potentiometer from Analog Devices/Maxim Integrated. It features two independent potentiometers with 32 tap positions each and a fixed end-to-end resistance of 10kΩ. Designed for audio applications, it operates on a single +4.5V to +5.5V supply with a standby current of 0.5µA. The device utilizes an SPI-compatible 3-wire serial interface for control and includes zero-crossing detection to minimize audible switching noise. It is housed in a 16-pin QSOP package and specified over the -40°C to +85°C temperature range.

Feature Summary

• Dual logarithmic taper potentiometers with 32 taps and 2dB step resolution
• Zero-crossing detection circuitry eliminates audible clicks during wiper transitions
• Integrated mute function providing -90dB attenuation
• SPI-compatible 3-wire serial interface with readback capability

Applications

• Stereo volume control circuits
• Fading and balancing stereo signals
• Replacement for mechanical potentiometers in audio equipment

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging as indicated by standard manufacturer conventions for this series. Confirm the specific package variant (QSOP) matches the design requirements. Ensure the voltage supply rails strictly adhere to the +4.5V to +5.5V specification to maintain electrical integrity.

Selection Notes

Select the MAX5410EEE+T when a dual-channel logarithmic response is required for audio signal processing. This model provides one wiper per potentiometer; choose the MAX5411 if two wipers per resistor are needed for complex fading applications. Ensure the system logic levels are compatible with the VLOGIC pin specifications.

Part Context

This component belongs to the MAX5408–MAX5411 family of dual audio digital potentiometers. The MAX5410 specifically denotes the dual-potentiometer variant with a single wiper per resistor and a 10kΩ nominal resistance. It shares the same functional architecture and interface protocols as the MAX5408, MAX5409, and MAX5411 models within the series.

Replacement Considerations

The MAX5408 serves as a direct functional substitute within the same package and pinout configuration. Both devices share identical serial interface commands and physical dimensions, allowing for straightforward interchangeability in existing designs requiring dual single-wiper potentiometers.
