Product Overview LA4725: Audio Power Amplifier, Class AB, 30W ? 2ch, BTL For complete documentation, see the data sheet Product Description 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, shorting to ground, load shorting, over-voltages and excessive temperatures) End Products Part Electrical Specifications Product Compliance Status Class Output VCC Max Power Typ (V) (W) Output Type ton Typ (ms) THD + N Typ (%) IQ Typ (mA) ISD Typ (nA) Package Type LA4725-E Pb-free Active AB 30 Dual 600 0.06 125 10000 SIP-14 16 For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016
