CM108AH - A High Integrated USB Audio I/O Controller

Download the CM108AH datasheet PDF. This datasheet also covers the CM108AH-C variant, as both devices belong to the same a high integrated usb audio i/o controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The CM108AH is a highly integrated single-chip USB audio solution.

All essential analog modules are embedded in the CM108AH, including dual DAC and earphone driver, ADC, microphone booster, PLL, regulator and USB transceiver modules.

Key Features

  • are programmable with jumper pins or by external EEPROM. Audio adjustments are easily controlled via specific HID-compliant volume control pins. An external codec or audio DSP can be connected to the CM108AH via I2S pin for further processing.
