ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified.
Note 3: An internal Zener on the GATE pins clamp the charge pump
voltage to a typical maximum operating voltage of 28V . External overdrive

of the GATE pin beyond the internal Zener voltage may damage the device.
The GATE capacitance must be <0.15糉 at maximum V
CC
. If a lower GATE
pin clamp voltage is desired, use an external Zener diode.
Note 4: The total supply current I
CC
is measured with V
CC1
and V
CC2
connected internally (LTC1647-1, LTC1647-2) or externally (LTC1647-3).
Note 5: The individual supply current I
CCX
is measured on the LTC1647-3.
The lower of the two supplies, V
CC1
and V
CC2
, will have its channels
current. The higher supply will carry the additional supply current of the
charge pump and the bias generator beside its channels current.
