• Manufacturer: Renesas Electronics Corporation.

M62436FP
The Focus gain can be reduced by connecting resistors between pins 14 and 15 and between pins 25 and 26. This has
the effect of improving the maximum input voltage (and the output noise voltage) characteristics. However, there is a
limitation on the maximum input voltage (Vl = 0.6 Vrms) due to the SRS sound block gain at f = 150 Hz.
