2•CH AUDIO POWER AMPLIFIER ˄2W x 2˅

DESCRIPTION

The SC7422 is a class AB power amplifier which designed dfuoarl

audio purpose. It can deliver 2W × 2 power output to theȍ4load in the

5V operation voltage. Total harmonic distortion is lower than 0.03%. hTe

output mode can be switched between the SE and BTL mohdee. T

volume also can be changed by a 32 steps volume controllerM. oreover,

the SC7422 requires a few extra components in the applicationi.s It

suitable for small or portable products.
