LA4631VC

Overview

The LA4631VC built-in a 2 channel single-ended output power amplifier that a power supply voltage range is wide and

has additionally the standby function to reduce the current drain. It is a power amplifier IC suitable for driving speaker of

various audio system equipments, which is especially useful for products that use batteries.

Functions

• Output power = 4.5W (typical)

(VCC = 12V, RL = 3Ω, THD+N = 10%)

• Built in standby function (Pin5)

• Built in thermal suht down circuit
