AD87010
Overview
AD87010 is an integrated audio system solution, embedding digital audio processing, power stage amplifier, and a stereo 2Vrms line driver. AD87010 is a digital audio amplifier capable of driving a pair of 8Ω,20W or a single 4Ω,40W speaker, both which operate with play music at a 24V supply.
