R2S15903SP
Sound Controller with Surround & AGC
REJ03F0159-0140
Rev.1.4
Dec 06, 2005
Description
The R2S15903SP is an optimum audio signal processor IC for TV. It has a 5ch input selector, AGC, surround/pseudo
stereo, tone control(2band), output gain control and 2ch master volume. It can control all of these functions with I2C
bus.
