LA4632 Datasheet | SANYO

Overview 10 W Two-Channel BTL AF Power Amplifier for Audio Applications The LA4632 is a pin patible version of the LA4631 (5 W × two channel single ended type) BTL power amplifier IC. The LA4632's pin patibility makes it possible to share a mon 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 ponents used differ. The LA4632 provides a full plement of built-in protection circuits, including protection against shorting to the power supply, shorting to ground, load shorting, and excessive temperatures.

When both channels are operating such that IOpeak = 1.0 A per channel is exceeded. If the IC is operated such that IOpeak = 1.0 A per channel is not exceeded, the IC can be used in the range 5.5 to 20 V (in the ranges where Pd max is not exceeded) with a load of RL = 4 to 8 Ω.
