2-Channel SE AF Power Amplifier
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)
• Built in standby function (Pin5)
• Built in thermal suht down circuit
(VCC = 12V, RL = 3Ω, THD+N = 10%)
