CHANNEL SWAP AND INVERSION

The WM8593 ADC input channels can be inverted and swapped in a number of ways to provide

maximum flexibility of input path to the ADC. The default configuration provides stereo output data

with the left and right channel data in the left and right channels. It is possible to swap the left and

right channels, invert them independently, or select the same data from both channels.

HIGH PASS FILTER

The WM8593 includes a high pass filter to remove DC offsets. The high pass filter response is

shown on page 93. It is possible to disable the high pass filter by writing to ADC_HPD.

ANALOGUE ROUTING CONTROL

The WM8593 has a number of analogue paths, allowing flexible routing of a number of analogue

input signals and DAC output signals at levels up to 2Vrms. The analogue paths include volume

control with zero cross, optional soft ramp and soft mute, and flexible routing of analogue inputs and

DAC outputs to analogue outputs.

There are a total of 16 (eight stereo) analogue input channels and four (two stereo) DAC output

channels. Any two of the sixteen input channels can be routed to the ADC. Any six of the 20 total

channels can be routed to the analogue outputs.
