Тема: R2S15900SP
Description
The R2S15900SP is an optimum audio signal processor IC for TV. It has a 5ch input selector, surround/pseudo stereo tone control(2band), output gain control and 2ch master volume. It can control all of these functions with I2 C bus.
Features
• Volume 0 to –84dB, –∞/ 1dB step | Each channel is independence control.
• 5 input selector + MUTE
• 2 Rec output
• Tone control Bass: –15dB to +15dB/ 1dB step | Treble: –15dB to +15dB/ 1dB step
• Surround <Low/ High> / Pseudo Stereo
• Mode selector Bypass/ Tone / Tone & Pseudo Stereo or Surround
• Output gain control 0dB/ +4.5dB
• I2C-BUS control
• Package 28pin SOP
