Shutdown  
The MAX9787 features a 0.2µA, low-power shutdown  
mode that reduces quiescent current consumption and  
extends battery life. Driving SHDN low disables the  
drive amplifiers, bias circuitry, and charge pump, and  
drives BIAS and all outputs to GND. Connect SHDN to

Click-and-Pop Suppression  
The MAX9787 speaker amplifiers feature Maxim’s com-  
prehensive, industry-leading click-and-pop suppres-  
sion. During startup, the click-and-pop suppression  
circuitry eliminates any audible transient sources inter-  
nal to the device. When entering shutdown, both ampli-  
fier outputs ramp to GND quickly and simultaneously.
