(2) Due to sharing of internal bias circuitry, the quiescent current, with all channels operating, is less than the single individual channel
quiescent current channels added together.
(3) Note that the I²C circuitry is still active while in disable mode. The current shown has no activity with the THS7313 I²C circuitry.
