The ● denotes the speciﬁcations which apply over the full operating temperature

range, otherwise speciﬁcations are at TA = 25°C. V12VIN = 12V, V5VIN = 5V, V3VIN = 3.3V, VVEEIN = –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

speciﬁed.

Note 3: The 5VGATE and 3VGATE pins should not be driven beyond the

lower of 12VIN + 0.3V and 14V.

Note 4: An internal clamp limits the GATE pins to a minimum of 5V above

VOUT (VEEIN for VEEGATE). Driving this pin to voltages beyond the clamp

may damage the device.

Note 5: The device pulls up the VEEOUT pin to 0.6V when pin is in open state.

Note 6: UHF package speciﬁcation 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 deﬁned as the deviation of a code from a

precise analog input voltage. Maximum speciﬁcations are limited by the

LSB step size and the single shot measurement. Typical speciﬁcations are

measured from 1/4, 1/2, 3/4 areas of the quantization band.

Note 9: Cb = total capacitance of one bus line in pF.
