Each channel is independent control.
• 5 input selector + MUTE with mono switch
• Input gain control 0dB to +20dB / 2dB step
• Tone control Bass : –14dB to +14dB / 2dB step
Treble : – 14dB to +14dB / 2dB step
• Surround Low / High
• Mode selector Bypass / Tone / Tone & Surround
• I2C-bus control
• Package SOP with 28 pin
Application
• Mini stereo, TV, etc.
Recommended Operating Condition
• Supply voltage …… VCC = 9.0V (typ)

7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications
or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality
and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or
undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall
have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
