LA4725

Ordering number : EN5715A LA4725 Monolithic Linear IC 2-channel 30W BTL Audio Amplifier http://onsemi.com 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 = 4Ω, 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, shortin...
