5W 2-Channel AF Power Amplifier
Overview
The LA4631 (5W×2 channels) is a single-ended power amplifier that has a pin arrangement similar to the LA4632 BTL
power amplifier (10W×2 channels). The LA4631'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 LA4632 is provided in an SIP-12H
package, and that it is necessary to provide a hole for the LA4631 pin 13 if the same printed circuit board is to be shared.
Note also that certain external components differ.)
