... SSM2305 GAIN The SSM2305 has a default gain that can be reduced by using a pair of external resistors with a value calculated as follows: External Gain Settings = 296 kΩ/(37 kΩ POP-AND-CLICK SUPPRESSION Voltage transients at the output of audio amplifiers can occur when shutdown activates or deactivates. Voltage transients as low can be heard as audio pops in the speaker ...

... ESL, low ESR capacitor, usually of around 4.7 μF. This capacitor bypasses low frequency noises to the ground plane. For high frequency transient noise, 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 SSM2305 helps maintain efficient performance. Rev Page SSM2305 ...
