The MAX9787 combines a stereo, 2.2W audio power amplifier with an analog volume control in a single device. A high 90dB PSRR and low 0.01% THD+N ensures clean, low-distortion amplification of the audio signal. The analog volume control can be driven with a potentiometer, an RC-filtered PWM source, or a DAC output. A BEEP input allows the addition of alert signals from the controller to the audio path. Industry-leading, click-and-pop suppression eliminates audible transients during power and shutdown cycles. Other features include single-supply voltage, a shutdown mode, logic-selectable gain, thermal-overload, and output short-circuit protection. The MAX9787 is offered in a space-saving, thermally efficient, 28-pin, thin QFN (5mm x 5mm x 0.8mm) package, and is specified over the extended -40C to +85C temperature range. |
