Note 1: Absolute maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2: All voltage values are with respect to ground with GND, OGND and
GND wired together unless otherwise noted.
Note 3: When these pin voltages are taken below ground or above VDD,
they will be clamped by internal diodes. This product can handle input
currents of 100mA below ground or above VDD without latchup.
Note 4: When these pin voltages are taken below ground, they will be
clamped by internal diodes. This product can handle input currents of
100mA below ground without latchup. These pins are not clamped to VDD.
Note 5: VDD = 4.75V to 5.25V, fSAMPLE = 1.25MHz, tr = tf = 2ns unless
otherwise specified.
Note 6: Linearity, offset and full-scale specifications apply for a single-
ended input on any channel with COM grounded.
Note 7: Integral nonlinearity is defined as the deviation of a code from a
straight line passing through the actual end points of the transfer curve.
The deviation is measured from the center of the quantization band.
Note 8: Bipolar offset is the offset voltage measured from – 0.5LSB when
the output code flickers between 0111 1111 1111 and 1000 0000 0000 for
LTC1851 and between 01 1111 1111 and 10 0000 0000 for LTC1850.
Note 9: Guaranteed by design, not subject to test.
Note 10: Recommended operating conditions.
Note 11: The falling CONVST edge starts a conversion. If CONVST returns
high at a critical point during the conversion it can create small errors. For
the best results, ensure that CONVST returns high either within 400ns
after the start of the conversion or after BUSY rises.
Note 12: The analog input range is determined by the voltage on
REFCOMP. The gain error specification is tested with an external 4.096V
but is valid for any value of REFCOMP.
The q denotes the specifications which apply over the full operating temperature
range, otherwise specifications are at TA = 25°C. (Note 5)
