MAX9711ETC+TGC1

Audio Amplifiers Overview

The MAX9711ETC+TGC1 is a mono 3W 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 features an industry-leading 100dB power-supply rejection ratio (PSRR). The device delivers 3W into a 3Ω load at 1% THD+N and includes ultra-low 0.005% THD+N, click-and-pop suppression, and a low-power shutdown mode consuming 0.5µA. It is specified over the -40°C to +85°C temperature range and housed in a 12-pin thin QFN package.

Audio Amplifiers Feature Summary

• Industry-leading 100dB PSRR for operation on noisy supplies
• Ultra-low 0.005% THD+N for clean amplification
• Comprehensive click-and-pop suppression during power cycles
• Low-power shutdown mode with 0.5µA current consumption

Audio Amplifiers Applications

• Notebook PCs
• Flat-Panel TVs
• Flat-Panel PC Displays
• Two-Way Radios
• Powered Speakers

Audio Amplifiers Procurement Notes

Verify the exact suffix TGC1 against official manufacturer documentation, as standard datasheets list ETC. Confirm RoHS compliance status and lead-free specifications directly with the supplier or manufacturer before procurement. Ensure the component matches the 12-pin thin QFN-EP physical footprint and thermal pad requirements specified for the MAX9711 series.

Audio Amplifiers Selection Notes

Select this component for mono audio applications requiring high power efficiency and noise immunity from a single 5V supply. The BTL configuration eliminates the need for large DC-blocking capacitors. Consider the 12-pin thin QFN package for space-constrained designs. Verify that the application load impedance supports the desired output power levels without exceeding thermal dissipation limits.

Audio Amplifiers Part Context

The MAX9711 is part of the MAX9710/MAX9711 family of 3W mono/stereo BTL audio power amplifiers. While the MAX9710 provides stereo output in a 20-pin package, the MAX9711 offers a mono configuration in a compact 12-pin thin QFN package. Both share identical electrical characteristics, including PSRR, THD+N, and protection features, tailored for portable and display audio systems.

Audio Amplifiers Replacement Considerations

The MAX9710 serves as a functional alternative for stereo applications but requires a 20-pin package. No direct mono pin-compatible substitutes are explicitly confirmed in the provided source material.
