24-bit 192kHz 2Vrms Multi-Channel CODEC  
DESCRIPTION  
FEATURES  
•
Multi-channel CODEC with 5 stereo input selector and 3  
stereo output selector  
The WM8594 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 WM8594 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.  
ADC: 100dB SNR typical (‘A’ weighted @ 48kHz)  
ADC: -90dB THD typical  
The WM8594 outputs three stereo audio channels at line  
levels up to 2Vrms, which can be selected from any of the  
analogue inputs and DAC outputs. Additionally, one stereo  
output is available with a headphone driver. The DAC  
channels include independent digital volume control, and all  
three stereo output channels include analogue volume  
control with soft ramp.

Independent sampling rates for ADC, DAC1 and DAC2  
DACs sampling frequency 32kHz to 192kHz  
ADC sampling frequency 32kHz to 96kHz  
ADC digital gain control: +30dB to -97dB  
DAC digital volume control: +12dB to -100dB  
Analogue Volume control with soft ramp: +6dB to -73.5dB  
The WM8594 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.  
All volume controls include zero cross detection to prevent  
pops and clicks  
•
2 and 3-wire serial control interface with readback and  
hardware reset, mute and powerdown pins  
The WM8594 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 and 3-wire control with full readback. Control of  
mute, powerdown and reset can also be achieved by pin  
selection.  
•
•
3.3V / 9V analogue, 3.3V digital supply operation  
48-lead TQFP package  
The WM8594 is available in a 48-lead TQFP package.
