Description for the TAS5806MD
The TAS5806MD 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 TAS5806MD 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, for applications under 10 W designers can leverage inexpensive ferrite bead filters to reduce board space and system cost. The device has an integrated DirectpathTM Headphone amplifier and line driver to increase the system-level integration and reduce total solution costs.
