Monolithic Linear IC
LA4635B
For General Audio Use
2-Channel BTL AF Power Amplifier
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
compatible with V
CC
= 9 V and V
CC
= 12 V specifications
and is available in two versions with different voltage
gains (LA4635B with VG = 45 dB and LA4635A with VG
= 35 dB).
