... SSM2311 amplifiers. The SSM2311 also offers protection circuits for overcurrent and temperature protection. GAIN The SSM2311 has a default gain of 18 dB, but can be reduced by using a pair of external resistors with a value calculated as follows: External Gain Settings = 300k/(37.5k + Rext) POP-AND-CLICK SUPPRESSION Voltage transients at the output of audio amplifiers can occur when shutdown is activated or deactivated ...

... This capacitor bypasses low frequency noises to the ground plane. For high frequency transients noises, use a 0.1 μF capacitor as close as possible to the VDD pin of the device. Placing the decoupling capacitor as close as possible to the SSM2311 helps maintain efficiency performance. Rev Page ...
