A6850
Dual Channel Switch Interface IC
Ganging SENSE1 and SENSE2
In certain applications both outputs may be read with a
single ADC channel. The OUTPUTx loads are enabled by
alternatively activating ENABLEx. In fact, both ENABLE1
and ENABLE2 may be activated simultaneously, with the
SENSE1 and SENSE2 currents added together. For valid
measurements the load resistor need only be selected so that
VSENSEx remain within specification.
