WM8593
24-bit 192kHz 2Vrms Multi-Channel CODEC
DESCRIPTION
FEATURES
The WM8593 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
independent volume control and clocking, and a range of
input/output channel selection options for flexible routing
within current and future audio systems.
The WM8593 has an eight stereo input selector which
accepts input levels up to 2Vrms. One stereo input can be
routed to the ADC. All inputs can be routed to an output
selector.
The output selector inputs two DAC channels and all
analogue bypass inputs, and outputs three independent
stereo channels at 2Vrms line level. The DAC channels
include independent digital volume control, and all three
output channels include analogue volume control.
• Multi-channel CODEC with 8 stereo input selector and 3
stereo output selector
• 4-channel DAC, 2-channel ADC
• 8x2Vrms stereo input selector with 8x2 channel analogue
bypass to output selector
• 3x2Vrms stereo output selector
• Audio performance
- DAC: 100dB SNR typical (‘A’ weighted @ 48kHz)
- DAC: -90dB THD typical
- ADC: 100dB SNR typical (‘A’ weighted @ 48kHz)
- ADC: -90dB THD typical
• Independent sampling rate for ADC and DACs
• Independent sampling rate for DAC1 and DAC2
• DACs sampling frequency 32kHz – 192kHz
• ADC sampling frequency 32kHz – 96kHz
The WM8593 is ideal for audio applications requiring high
performance and flexible routing options, including flat panel

The device is controlled via a serial interface with support
for 2-wire and 3-wire control with readback. Control of mute,
powerdown and reset can also be achieved by pin selection.
The WM8593 is available in a 64-lead TQFP package.
