TPA2014D1 - Texas Instruments

TPA2014D1 1.5-W CONSTANT OUTPUT POWER CLASS-D AUDIO AMPLIFIER

The TPA2014D1 is a high efficiency Class-D audio power amplifier with an integrated boost converter. It drives up to 1.5 W (10% THD+N) into a 8 Ω speaker from a 3.6 V supply. With 85% typical efficiency, the TPA2014D1 helps extend battery life when playing audio. The built-in boost converter generates a higher voltage rail for the Class-D amplifier. This pro.
