VCOM output
One unbuffered common-mode voltage output pin, VCOM (pin 14) is brought out for decoupling purposes. This
pin is nominally biased to a dc voltage level equal to VCC/2. If this pin is to be used to bias external circuitry, a
voltage follower is required for buffering purposes. Figure 8 shows an example of using the VCOM pin for external
biasing applications.

zero flag
zero detect condition
Zero detection for each output channel is independent from the others. If the data for a given channel remains
at a 0 level for 1024 sample periods (or LRCK clock periods), a zero detect condition exists for that channel.
zero output flag
When the data for all channels remains at a 0 level for 1024 sample periods (or LRCK clock periods), the ZEROA
(pin 6) is set to a logic 1 state. The zero flag pin can be used to operate external mute circuits, or used as a status
indicator for a microcontroller, audio signal processor, or other digitally controlled functions.
