(1) Device electrical characteristics are over Section 5.4 unless otherwise noted.
(2) All voltage values are with respect to the ground pins (VSS).
(3) To prevent excess current, the supply voltage delta | VDDI – VDD | must be less than the specified limit.
(4) Supply power dissipation based on non–compressed commands and data.
(5) To prevent excess current, the supply voltage delta | VBIAS – VOFFSET | must be less than the specified limit.
(6) Supply power dissipation based on 3 global resets in 200 µs.
