SC7422
2-CH AUDIO POWER AMPLIFIER 2W x 2
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
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.
