SC7422S

SC7422 2-CH AUDIO POWER AMPLIFIER DESCRIPTION The SC7422 is a class AB power amplifier which designed for dual audio purpose. It can deliver 2W × 2 power output to the 4 load in the SOP-16-375-1.27 2W x 2 5V operation voltage. Total harmonic distortion is lower than 0.03%. The output mode can be switched between the SE and BTL mode. The volume also can be changed by a 32 steps volume controller. Moreover, the SC7422 requires a few extra components in the application. It is suitable for small or portable products.
