HS-100B is a highly integrated single chip USB audio solution. All essential analog modules are embedded in HS-100B, including dual DAC and headphone amplifier, ADC, microphone booster, PLL, crystal-less design, regulator, anti-pop circuitry 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.
