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

Featuring TI’s proprietary Hybrid Modulation scheme, the TAS5805M consumes very-low quiescent 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 filters to reduce board space and system cost.
