adg436 rev. b | page 11 of 12 applications information adg436 supply voltages the adg436 can operate from a dual or single supply. v ss should be connected to gnd when operating with a single supply. when using a dual supply, the adg436 can also operate with unbalanced supplies, for example v dd = 20 v and v ss = ?5 v. the only restrictions are that v dd to gnd must not exceed 30 v, v ss to gnd must not drop below ?30 v, and v dd to v ss must not exceed +44 v. it is important to remember that the adg436 supply voltage directly affects the input signal range, the switch on resistance and the switching times of the part. the effects of the power supplies on these characteristics can be clearly seen from the typical performance characteristics curves. power-supply sequencing when using cmos devices, care must be taken to ensure correct power-supply sequencing. incorrect power-supply sequencing can result in the device being subjected to stresses beyond those listed in the absolute maximum ratings. always sequence v dd on first followed by v ss and the logic signals. an external signal can then be safely presented to the source or drain of the switch.
