Description
AD62552A is a single chip integrated headphone driver, DAC, ADC and microphone booster. AD62552A can drive up to 70m W @16Ω. The device also has a master mode I2S input port and output port. The I2S input port allows other external audio sources to be recorded by host and mixed to headphone. The I2S output port allows other high performance audio device (i.e. AD82550A/AD8256A/AD8356A) to be controlled by AD62552A.
