 ELECTRICAL CHARACTERISTICS
 
The l denotes the speci cations which apply over the full operating
temperature range, otherwise speci cations are at T
A
 = 25癈. V
DD
 = 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 pins are positive; all voltages are referenced to 
GND unless otherwise speci ed.
Note 3: An internal clamp limits the GATE pin to a minimum of 5V above 
SOURCE. Driving this pin to voltages beyond the clamp may damage the device.
Note 4: Offset error is the offset voltage measured from 1LSB when the 
output code  ickers between 0000 0000 and 0000 0001.
Note 5: 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 the 1/4, 1/2 and 3/4 areas of the quantization band.
Note 6: Guaranteed by design and not subject to test.
