onsemi LA4725
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.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
