The 92HD99 audio CODEC provides stereo 24- bit, full duplex resolution supporting sample rates up
to 192kHz by the DAC and ADC.
An integrated BTL stereo amplifier is ideal for driving 4ohm or 8ohm integrated speakers in mobile
and ultra-mobile computers. For desktop computers or mobile computers using only one speaker,
the BTL output stage may be configured to support a single mono speaker.
Port presence detect capabilities allow the CODEC to detect when audio devices are connected to
the CODEC. The fully parametric Internal EQ can be initiated upon headphone jack insertion and
removal for protection of notebook speakers.
The 92HD99 audio CODEC operates with a 3.3V digital supply and a 5V (4.75V allowed when using
external voltage regulator) analog supply. It allows for 1.5V and 3.3V HDA signaling; the correct sig-
nalling level is selected dynamically based on the power supply voltage on the DVDD-IO pin.
The 92HD99 audio CODEC is offered in a 40-pin QFN Environmental (ROHS) package.
Add an “8” to the end for tape and reel delivery.
yy = silicon stepping/revision, contact sales for current data.
