Description The IRS20124 is a high voltage, high speed power MOSFET driver with internal deadtime and shutdown functions specially designed for Class D audio amplifier applications. The internal dead time generation block provides accurate gate switch timing and enables tight deadtime settings for better THD performances. In order to maximize other audio performance characteristics, all switching times are designed for immunity from external disturbances such as VCC perturbation and incoming switching noise on the DT pin. Logic inputs are compatible with LSTTL output or standard CMOS down to 3.0 V without speed degradation. The output drivers feature high current buffers capable of sourcing 1.0 A and sinking 1.2 A. Internal delays are optimized to achieve minimal deadtime variations. Proprietary HVIC and latch immune CMOS technologies guarantee operation down to Vs= –4 V, providing outstanding capabilities of latch and surge immunities with rugged monolithic construction.

Circuit Description 1000W Power Amplifier: Power amplifier has up to 1000 Watt power, this circuit made one channel only so if you want to create a stereo in it must be made one again, actually this is more suitable power amplifier in use for Sound System or outdoor, so if only in use for the house I think is less suitable. Maybe you've seen or even have an active speaker and there is written 1500 watts PMPO (Peak Music Power Output), make no mistake this is different from Power Amplifier Active Speaker, I often dismantle such Active Speaker in it only a power with power no more than 150 watts by using the transformer 2-3 Ampere. PMPO is not a real power which is issued by the Power Amplifier, but counting all the speakers that there is, for example: if there are 5 pieces of speakers on each channel and each speaker has a power of 10 W then it is 100 W PMPO.
