CM108AH is a highly integrated single chip USB audio solution. All essential analog modules are embedded in CM108AH, including dual DAC and headphone amplifier, ADC, microphone booster, PLL, regulator and USB transceiver. Many features are programmable with jumper pins or external EEPROM.
In addition, audio adjustment can be easily controlled via specific HID compliant volume control pins. For value added application, external codec or audio DSP can be connected to CM108AH via I2S pin for further processing. 3 GPIO pins can be accessed with customer application software for additional value added application.
