CS5501 CS5503
to ensure that logic inputs are maintained at either
VD+ ar DGND potential when SLEEP is low.
Note that battery life could be shortened if the +5 V
supply drops slowly during power-down. As the
supply drops below the battery voltage but not yet
below the logic threshold of the SLEEP pin, the
battery will be supplying the CS5501/CS5503 at
full power (typically 3 mA). Faster transitions at
SLEEP can be triggered using a resistive divider or
a simple resistor network to generate the SLEEP in-
put from the +5 V supply.
Output Loading Considerations
To maximize performance of the CS5501/ CS5503,
the output drive currents from the digital output
lines should be minimized.
