MAX9711：3W Mono/Stereo BTL Audio Power Amplifiers with Shutdown

3W Mono/Stereo BTL Audio Power Amplifiers with Shutdown Feature Industry-Leading PSRR

The MAX9710/MAX9711 are stereo/mono 3W bridge-tied load (BTL) audio power amplifiers. These devices are PC99/01 compliant, operate from a single 4.5V to 5.5V supply, and feature an industry-leading 100dB PSRR, which allows these devices to operate from noisy supplies without additional, costly power-supply conditioning. An ultra-low 0.005% THD+N ensures clean, low-distortion amplification of the audio signal while click-and-pop suppression eliminates audible transients on power and shutdown cycles. Power-saving features include low 2mV VOS (minimizing DC current drain through the speakers), low 7mA supply current, and a 0.5µA shutdown mode. A MUTE function allows the outputs to be quickly enabled or disabled. These devices include thermal overload protection, are specified over the extended -40°C to +85°C temperature range, and are supplied in thermally efficient packages. The MAX9710 is available in a 20-pin thin QFN package (5mm x 5mm x 0.8mm). The MAX9711 is available in a 12-pin thin QFN package (4mm x 4mm x 0.8mm).
