(3) Due to sharing of internal bias currents, the quiescent current, with all channels operating, is less than the single individual channel
quiescent currents added together.
(4) Note that the I²C circuitry is still active while in Disable mode. The current shown is while there is no activity with the THS7303’s I²C
circuitry.
