TAS5806M 23W stereo, digital closed-loop Class-D audio amplifier with processing

 

Description

The TAS5806M 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 the TI proprietary Hybrid Modulation scheme, the TAS5806M consumes low quiescent current (16.5 mA at 13.5 V PVDD), extending battery life in portable audio applications. With advanced EMI suppression technology, for applications under 10 W designers can leverage inexpensive ferrite bead filters to reduce board space and system cost.
