The ?/SPAN> denotes the speci cations which apply over the full operating temperature
range, otherwise speci cations are at T
A
= 25癈. V

= 12V, unless otherwise noted.
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 GND unless otherwise
speci ed.
Note 3: The 5V
GATE
and 3V
GATE
pins should not be driven beyond the
lower of 12V
IN
+ 0.3V and 14V.
Note 4: An internal clamp limits the GATE pins to a minimum of 5V above
V
OUT
(V
EEIN
for V
EEGATE
). Driving this pin to voltages beyond the clamp
may damage the device.
Note 5: The device pulls up the V
EEOUT
pin to 0.6V when pin is in open state.
Note 6: UHF package speci cation limits are identical to G package limits
and guaranteed by design and by correlation to wafer test measurements.
Note 7: Guaranteed by design and not subject to test.
Note 8: Integral Nonlinearity is de ned as the deviation of a code from a
precise analog input voltage. Maximum speci cations are limited by the
LSB step size and the single shot measurement. Typical speci cations are
measured from 1/4, 1/2, 3/4 areas of the quantization band.
Note 9: C
b
= total capacitance of one bus line in pF.
