The TAS5806MD is a 23-W Stereo, 45-W Mono, 4.5 to 26.4-V, Digital Input Class-D Audio Amplifier with Processing and P2P HP

The TAS5806MD is a high-efficiency, stereo, closed-loop, Class-D ADR364AUJZ-REEL7 amplifier that provides a cost-effective digital input solution with low power consumption and rich sound. The device's integrated audio processor and 96 kHz architecture support advanced audio processing pipelines including SRC, 15 BQs per channel, volume control, audio mixing, 3-band 4-order DRC, full-band AGL, THD manager, and level meters.

Using 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 techniques, for applications below 10 W, designers can take advantage of inexpensive ferrite bead filters to reduce board space and system cost. The device features an integrated Directpath TM headphone amplifier and line driver, which improves system-level integration and reduces overall solution cost.
