Description
AD6255A is a single chip of Class-D audio
amplifier with USB/I2S interface an d sup ports
recording function. When using the po wer supplied
from the USB port, AD6 255A can drive a pair of u p
to 1W spe akers d ue to the built-in, hig h ef ficiency
and hig h p erformance class D am plifiers. Th e
device also has an I2S input port and I2S output port.
The I 2S input port allo ws oth er ex ternal a udio
sources t o u se t he cla ss D amplif ier t o sha re t he
speakers. Th e I 2S output port allows other high
performance audio device (i.e. AD8356A/AD8256A)
to be controlled by AD6255A.
