HAA3603B General Description:
The HAA3603B is an analog input, stereo, high efficiency Class D audio power amplifier. It requires minimal external components and operates a single 8V to 14.4V power supply.
The device can driver 2x4Ω speakers and delivering 2X15W peak output power (THD+N=1%) at 12V power supply voltage. When PBTL mode, it can deliver up to 1x30W peak output power into a 2Ω speaker while offering up to 88.5% high efficiency.
The HAA3603B 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 HAA3603B 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 HAA3603B is available in ETSSOP-28L package.
