Description

This is a stereo digital audio amplifier with high power efficiency, which leads to longer battery life, less heat sink requirement, smaller board size and lower system cost. AD82550A can detect headphone connection and choose to drive either stereo loudspeakers or stereo headphones.

Operating with 3.0/3.3/5V loudspeaker driver supply, each loudspeaker channel AD82550A can typically deliver 0.8/1.0/2.3W to a 4 loudspeaker, respectively, with less than 1% THD+N. Operating with 3.0/3.3V headphone driver supply, each headphone channel can typically deliver 29/35mW to 32, 54/65mW to 16 and 94/113mW to 8, respectively, with less than 1% THD+N.
