LA4632
Overview
The LA4632 is a pin compatible version of the LA4631 (5W×2 channel single ended type) BTL power amplifier IC. The
LA4632's pin compatibility makes it possible to share a common printed circuit board among a series of end products
differentiated by power rank. Note that the LA4631 has a pin 13, and that it is necessary to provide a hole for this pin if the
same printed circuit board is to be shared. Also, some of the external components used differ. The LA4632 provides a full
complement of built-in protection circuits, including protection against shorting to the power supply, shorting to ground,
load shorting, and excessive temperatures.
