Audio Click-Pop Suppressor  
General Description  
Features  
The MAX9890 provides click-and-pop suppression for  
devices such as CODECs with integrated headphone  
amplifiers that lack a clickless/popless startup/power-  
up or shutdown/power-down. The device controls the  
ramping of the DC bias voltage on the output-coupling  
capacitors and the application of the audio signal to  
ensure that no audible transients are present at the  
headphones. The MAX9890A features a 200ms startup  
time for use with up to 100µF coupling capacitors. The  
MAX9890B features a 330ms startup time for use with  
greater than 100µF coupling capacitors.

ꢀ Requires Only One 0.1µF Capacitor to Coꢂplete  
the Circuit  
The MAX9890 consumes 14µA of supply current and  
0.001µA in shutdown, while contributing less than  
0.003% THD+N into a 32Ω load. ESD (Human Body  
Model) protection circuitry on the outputs protect the  
MAX9890 and devices further up the signal chain from  
ESD strikes up to 8kꢀ.
