Texas Instruments  TAS5805MPWPR

The TAS5805M is a high-efficiency, stereo, closed-loop Class-D amplifier offering acost-effective digital-input solution with low power dissipation and sound enrichment. The device’sintegrated audio processor and 96 kHz architecture support advanced audio process flow, includingSRC, 15 BQs per channel, volume control, audio mixing, 3-band 4th order DRC, full-band AGL, THDmanager and level meter.

Featuring TI’s proprietary Hybrid Modulation scheme, the TAS5805M consumes very-lowquiescent current (16.5 mA at 13.5 V PVDD), extending battery life in portable audio applications.With advanced EMI suppression technology, designers can leverage inexpensive ferrite bead filtersto reduce board space and system cost.
