AD87587-2X20W Stereo/1x40W Mono Digital Audio Amplifier with 2Vrms Line Driver DataSheet

Description
    The AD87587 is an integrated audio system solution,
embedding digital audio process, power stage
amplifier, and a stereo 2Vrms line driver.
Using I2C digital control interface, the user can control
AD87587’s input format selection, mute and volume
control functions. AD87587 has many built-in
protection circuits to safeguard AD87587 from
connection errors.
