LA4635A
Overview
The LA4635A is a 2-channel power amplifier that is pin-compatible 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 VCC = 9V and VCC = 12V specifications and is available in two versions with different
voltage gains (LA4635A with VG = 35dB and LA4635B with VG = 45dB).
