MAX5411EEE+T

Overview

The MAX5411EEE+T is a dual, logarithmic taper digital potentiometer featuring two wipers per resistor and 32 tap positions. It operates on a single +4.5V to +5.5V supply with a nominal end-to-end resistance of 10kΩ and a temperature coefficient of 35ppm/°C. The device utilizes an SPI-compatible 3-wire serial interface for control and includes zero-crossing detection to minimize audible switching noise. Packaged in a 16-pin QSOP, it supports mute functions down to -90dB and power-on reset to maximum attenuation.

Feature Summary

• Dual potentiometers with two wipers each and 32-tap logarithmic positions
• SPI-compatible 3-wire serial interface with readback capabilities
• Zero-crossing detection minimizes audible clicks during transitions
• Mute function provides -90dB attenuation

Applications

• Stereo volume control
• Fading and balancing stereo signals
• Mechanical potentiometer replacement in audio circuits

Procurement Notes

Verify the 'EEE' suffix indicates the 16-pin QSOP package and the '+' suffix denotes lead-free compliance. Confirm the 'T' suffix specifies tape-and-reel packaging rather than tube. Ensure the operating voltage range matches the +4.5V to +5.5V requirement specified for the MAX5411 variant.

Selection Notes

Select this component when a dual-channel log taper response is required for audio applications. The MAX5411 specifically offers two wipers per channel, unlike the MAX5410 which has one. Verify that the system logic levels are compatible with the VLOGIC pin (2.7V to 5.5V) and that the 10kΩ resistance value fits the circuit design constraints.

Part Context

This part belongs to the MAX5408–MAX5411 family of dual, audio, log taper digital potentiometers. While sharing core specifications like resistance and interface, the MAX5411 is distinguished by its dual-wiper architecture per potentiometer, enabling independent control of multiple signal paths within a single stereo channel.

Replacement Considerations

The MAX5411EUE+ is a direct pin-compatible alternative available in a 16-pin TSSOP package. Other family members like the MAX5410 offer single-wiper configurations but share similar electrical characteristics and interfaces.
