Overview
The LA4635A 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 compatible with V
CC
= 9 V and
V
CC
= 12 V specifications and is available in two versions
with different voltage gains (LA4635A with VG = 35 dB
and LA4635B with VG = 45 dB).
