MAX9726AEBP+T

Overview

The MAX9726AEBP+T is a stereo headphone amplifier from the DirectDrive series, designed for mobile applications. It operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 20-WFBGA package. The device features Class AB topology with integrated bass enhancement and digital volume control via I2C interface. Key electrical characteristics include low quiescent current consumption and support for rail-to-rail output driving headphones directly without external coupling capacitors.

Feature Summary

• Integrated bass enhancement technology for improved audio quality
• Digital volume control accessible through I2C interface
• DirectDrive capability eliminates need for output coupling capacitors
• Built-in protection against short circuits and thermal overload

Applications

• Mobile phone headphone amplifiers
• Portable media players
• Smartphones and tablets

Procurement Notes

Verify the specific suffix 'BP' indicates the WFBGA package variant distinct from other pinouts. Confirm RoHS compliance status as '+'. Check for obsolescence notices as Analog Devices frequently updates product lifecycles. Ensure design-in compatibility with existing I2C bus configurations in target devices.

Selection Notes

Select this component when space-constrained designs require integrated bass boost and digital control. Compare power efficiency against competing DirectDrive solutions. Verify that the 20-WFBGA footprint matches the PCB layout constraints. Consider thermal performance requirements given the compact package size and audio power delivery needs.

Part Context

This part belongs to Maxim Integrated's DirectDrive family of audio amplifiers. These components are optimized for portable electronics requiring high-quality audio playback with minimal external components. The MAX9726 series specifically targets mobile handsets and handheld devices where battery life and board space are critical design parameters.

Replacement Considerations

MAX9726AETP+T: Pin-compatible alternative using TQFN package instead of WFBGA.
