24-bit 192kHz 2Vrms Multi-Channel CODEC
DESCRIPTION
FEATURES
•
Multi-channel CODEC with 5 stereo input selector and 3
stereo output selector
The WM8599 is a high performance multi-channel audio
CODEC with flexible input/output selection and digital and
analogue volume control. Features include a 24-bit stereo
ADC with digital gain control, two 24-bit DACs with
•
•
4-channel DAC, 2-channel ADC
Five stereo 2Vrms stereo inputs with analogue bypass to
three stereo 2Vrms outputs
independent digital volume control, and
a range of
input/output channel selection options with analogue volume
control, for flexible routing within current and future audio
systems.

DAC: 100dB SNR typical (‘A’ weighted @ 48kHz)
DAC: -90dB THD typical
The WM8599 accepts five stereo audio inputs at line levels
up to 2Vrms. One stereo input can be routed to the ADC. All
inputs can be routed to the output.

Independent sampling rates for ADC and DACs
DACs sampling frequency 32kHz to 192kHz
ADC sampling frequency 32kHz to 96kHz
The WM8599 outputs three stereo audio channels at line
levels up to 2Vrms, which can be selected from any of the
analogue inputs and DAC outputs. The DAC channels
include independent digital volume control, and all three
stereo output channels include analogue volume control
with soft ramp.
ADC digital gain control: +30dB to -97dB
DAC digital volume control: +12dB to -100dB
Analogue Volume control with soft ramp: +6dB to -73.5dB
All volume controls include zero cross detection to prevent
pops and clicks
The WM8599 supports up to 2Vrms analogue inputs, 2Vrms
outputs, with sampling rates from 32kHz to 192kHz for the
DACs, and 32kHz to 96kHz for the ADC.
•
2-wire serial control interface with readback and hardware
reset, mute and powerdown pins
The WM8599 is ideal for audio applications requiring high
performance and flexible routing options, including flat panel
digital TV and DVD recorder.
•
•
Master or slave clocking modes
Programmable format audio data interface modes
-
I2S, LJ, RJ, DSP
The device is controlled via a serial interface with support
for 2-wire control with readback. Control of mute,
powerdown and reset can also be achieved by pin selection.
