MAX9711ETC+TG51

Audio Amplifiers Overview

The MAX9711ETC+TG51 is a mono 3W bridge-tied load (BTL) audio power amplifier from Analog Devices Inc./Maxim Integrated. It operates from a single 4.5V to 5.5V supply and features an industry-leading 100dB PSRR at 1kHz. The device delivers 3W into a 3Ω load with 1% THD+N and achieves ultra-low distortion of 0.005%. Quiescent current is 7mA, with a shutdown mode consuming only 0.5µA. It includes click-and-pop suppression, thermal overload protection, and a MUTE function. The component is housed in a 12-pin thin QFN package (4mm x 4mm x 0.8mm) and operates over an extended temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Ultra-high 100dB power-supply rejection ratio for operation on noisy supplies
• Comprehensive click-and-pop suppression during power and shutdown cycles
• Low-power shutdown mode reducing quiescent current to 0.5µA
• Thermal overload protection with automatic recovery

Audio Amplifiers Applications

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

Audio Amplifiers Procurement Notes

Verify the exact ordering suffix matches the required package and temperature grade. Confirm that the '+T' or similar suffix indicates tape-and-reel packaging if reel quantity is critical for assembly. Ensure the manufacturer designation aligns with current corporate structures following acquisitions. Cross-reference the date code against production timelines to verify component freshness and storage conditions prior to installation.

Audio Amplifiers Selection Notes

Select this component for mono audio applications requiring high efficiency and low distortion from a single 5V supply. The 12-pin thin QFN package suits space-constrained designs. Ensure the load impedance supports the desired output power without exceeding thermal limits. Verify that the input signal levels are compatible with the gain setting resistors to prevent clipping while maintaining the specified THD+N performance across the operating frequency range.

Audio Amplifiers Part Context

This part belongs to the MAX9710/MAX9711 family of BTL audio amplifiers. While the MAX9710 offers stereo capability in a 20-pin package, the MAX9711 provides mono amplification in a more compact 12-pin form factor. Both share identical electrical characteristics regarding power output, PSRR, and protection features, differing primarily in channel count and physical footprint.
