DESCRIPTION
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 with analogue volume
control 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 WM8593 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.
The WM8593 supports up to 2Vrms analogue inputs, 2Vrms
outputs, with sample rates from 32kHz to 192kHz on the
DACs, and 32kHz to 96kHz on the ADC.
The WM8593 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.
The WM8593 is ideal for audio applications requiring high
performance and flexible routing options, including flat panel
digital TV and DVD recorder.
The WM8593 is available in a 64-lead TQFP package.
