LA4725
Overview
The LA4725 is a 2-channel BTL audio power amplifier IC for Car audio. It was designed for the best possible audio quality
and features an extended low band roll-off frequency provided by a newly-developed NF circuit that does not require an
external capacitor. Furthermore, crosstalk, which can cause muddiness in the audio output, has been significantly reduced
by both circuit and wiring pattern improvements. Thus this amplifier can provide powerful lows and clear highs.
Features
Total output (EIAJ power): 30W+30W (at VCC = 14.4V, RL = 4, THD = 30%)
High-fidelity design (fL < 10Hz, fH = 130kHz)
Extremely low impulse noise levels
An arbitrary amplifier startup time can be set up with external components
built-in standby switch circuit
Full complement of built-in protection circuits (includes circuits that protect against shorting to VCC, shorting to ground,
load shorting, over-voltages and excessive temperatures)
