AD87010-LG48NRY
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.
Using I²C digital control interface, the user can control AD87010’s input format selection, mute and volume control functions. AD87010 has many built-in protection circuits to safeguard AD87010 from connection errors.
