ASAHI KASEI
<Analog Mixing Circuit for Receiver Output>
When AIN3 bit = “0”, DACL, MINL, LINL2 and RINR2 bits controls each path switch.
MIN path mixing gain is +6dB(typ)@LOVL bit = “0” when the external input resistance is 20kΩ.
LIN2, RIN2 and DAC pathes mixing gain is 0dB(typ)@LOVL bit = “0”.
When AIN3 bit = “1”, DACL, LINL2, RINR2, LINL3, RINR3, MICL3 and MICR3 bits controls each path switch. All
pathes mixing gain is 0dB(typ)@LOVL bit = “0”.
