Overview

The LA4635B is a 2-channel power IC that is pin-compat-

ible with the LA4636.

It represents a new concept in devices of this type by

allowing design editing based on common circuit board pin

compatibility for products of different power ranks. It is

and is available in two versions with different voltage

gains (LA4635B with VG = 45 dB and LA4635A with VG

= 35 dB).
