HAA3605 General Description:
The HAA3605 is an analog input, stereo, high efficiency Class D audio power amplifier. It operates from 4.5V to 16V power supply and can driver 2x4Ω speakers and delivering 2X25W peak output power (THD+N=1%) at 16V supply voltage.
The HAA3605 features PLAGC technology which constantly monitors output power and dynamically adjust internal gain to prevent long time overstress across the speaker. It also prevents clip-noise while playing music.
The HAA3605 features SSM (spread spectrum modulation), AERC (active edge rate control) and De-phase function to suppress EMI which enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction.
The HAA3605 features UVP (under-voltage protection), OVP (over-voltage protection), DC speaker protection, OCP (over-current protection), OTP (over-temperature protection). All of these protections can be recovered automatically.
The HAA3605 is available in ETSSOP-28L package.
