MAX9710ETP+TGC1

Audio Amplifiers Overview

The MAX9710ETP+TGC1 is a stereo bridge-tied load (BTL) audio power amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 4.5V to 5.5V supply and delivers up to 3W into a 3Ω load with 1% THD+N. Key electrical parameters include a quiescent supply current of 7mA, a shutdown current of 0.5µA, and an industry-leading 100dB power-supply rejection ratio (PSRR). The device features ultra-low 0.005% THD+N, click-and-pop suppression, and thermal overload protection. It is housed in a 20-pin thin QFN package and specified for operation over the -40°C to +85°C temperature range.

Audio Amplifiers Procurement Notes

Verify the specific suffix TGC1 against official manufacturer documentation, as standard datasheets typically list ETP. Confirm RoHS compliance status (+ suffix) and availability through authorized distributors. Ensure the ordering information matches the exact pin configuration and thermal pad requirements for your PCB layout.

Audio Amplifiers Selection Notes

Select this component for stereo audio applications requiring high PSRR and low distortion within a 5V single-supply system. The 20-pin thin QFN package is suitable for space-constrained designs. Consider the thermal dissipation characteristics and ensure adequate ground plane connection via the exposed pad for optimal performance.

Audio Amplifiers Part Context

This part belongs to the MAX9710/MAX9711 family of 3W mono/stereo BTL audio power amplifiers. The MAX9710 variant provides stereo output channels, while the MAX9711 offers a mono configuration. Both share identical electrical characteristics, shutdown functionality, and click-and-pop suppression technologies designed for noisy supply environments.

Audio Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing circuit designs before considering alternative components.

Audio Amplifiers FAQ

How does the device handle click-and-pop suppression?

The device uses an S-shaped waveform ramp for the common-mode bias voltage during startup and actively drives outputs low simultaneously during shutdown to minimize energy in the audio band.

What is the function of the BIAS pin?

The BIAS pin provides an internally generated, power-supply-independent common-mode bias voltage of 2.5V, which sets the DC bias level for audio outputs and supports click-and-pop suppression.

How is the MUTE function controlled?

Drive the MUTE input high to mute the device, disconnecting the input from the amplifier. Drive it low for normal operation.
