The stereo 32 Ohm headset pair of drivers also includes a mixer of a LINEL and LINER pair of
stereo inputs, as well as a differential monaural auxiliary input (line level).
The DAC output can be connected through a buffer stage to the input of the audio power ampli-
fier, using 2x coupling capacitors The mono buffer stage also includes a mixer of the LINEL and
LINER inputs, as well as a differential monaural auxiliary input (line level) which can be, for
example, the output of a voice Codec output driver in mobile phones.
The audio power amplifier is a dual-mode AB class amplifier with differential output and pro-
grammable volume control. In full power mode, it is capable of driving an 8-ohm loudspeaker at
maximum power of 1W at 5V supply and 440 mW at 3.6V supply. In low power mode, it can
drive the same loudspeaker as an earpiece, making it suitable as a handsfree speaker driver in
wireless handset application. The volume, mute, power down, de-emphasis controls and 16-bit,
18-bit and 20-bit audio formats are digitally programmable via a 4-wire SPI bus and the digital
audio data are provided through a multi-format I2S interface.
