MAX9719CEUE+T

Audio Amplifiers Overview

The MAX9719CEUE+T is a stereo audio power amplifier from the MAX9718/MAX9719 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 5.5V and delivers 1.4W of continuous average power per channel into a 4Ω load with less than 1% THD+N at a +5V supply. The device features a bridge-tied load (BTL) architecture, differential inputs for improved noise rejection, and internally fixed gain options including 0dB, 3dB, and 6dB. It incorporates comprehensive click-and-pop suppression circuitry and a low-power shutdown mode that reduces quiescent current consumption to less than 100nA.

Audio Amplifiers Feature Summary

• Bridge-tied load (BTL) architecture minimizes external component count while delivering high-quality audio amplification.
• Differential input structure improves noise rejection and provides common-mode rejection capabilities.
• Industry-leading click-and-pop suppression circuitry reduces audible artifacts during startup and shutdown sequences.
• Low-power shutdown mode disables bias generators and amplifiers, significantly reducing quiescent current consumption.

Audio Amplifiers Applications

• Mobile Phones
• PDAs
• Portable Devices

Audio Amplifiers Procurement Notes

Verify the specific suffix 'CEUE' against official manufacturer documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with the required PCB footprint and thermal management strategy for the selected package variant. Confirm availability through authorized distributors as stock levels fluctuate.

Audio Amplifiers Selection Notes

Select this component for portable applications requiring stereo audio output with minimal external components. The internal fixed gain simplifies design compared to adjustable versions. Consider the BTL configuration benefits over single-ended designs for higher power delivery without DC-blocking capacitors. Evaluate thermal dissipation requirements based on the specific operating conditions and load impedance.

Audio Amplifiers Part Context

The MAX9719CEUE+T belongs to the MAX9718/MAX9719 series of low-cost, mono/stereo audio power amplifiers designed for portable devices. This series offers a pin-compatible upgrade path to other similar amplifiers like the LM4895. The MAX9719 specifically serves as the dual-channel (stereo) counterpart to the single-channel MAX9718, sharing identical electrical characteristics and feature sets.

Audio Amplifiers Replacement Considerations

The MAX9718 is noted as pin-compatible with the LM4895. For direct replacements within the same family, verify specific gain configurations and package types. Consult official substitution guides for equivalent performance in terms of power output and supply voltage ranges.
