MAX9710

19-2841; Rev 0; 4/03 3W Mono/Stereo BTL Audio Power Amplifiers with Shutdown General Description 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, www.DataSheet4U.com low-distortion amplification of the audio signal while patented 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 either a 20-pin thin QFN package (5mm ✕ 5mm ✕ 0.8mm) or a 16-pin TSSOP-EP package. The MAX9711 is available in a 12pin thin QFN package (4mm ✕ 4mm ✕ 0.8mm). o 3W into 3Ω (1% THD+N) o 4W into 3Ω (10% THD+N) o Industry-Leading, Ultra-High 100dB PSRR o PC99/01 Compliant o Patented Click-and-Pop Suppression o Low 0.005% THD+N o Low Quiescent Current: 7mA o Low-Power Shutdown Mode: 0.5µA o MUTE Function o Tiny 20-Pin Thin QFN (5mm ✕ 5mm ✕ 0.8mm) and 16-Pin TSS...
