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 -40°C to +85°C temperature range.
