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 DGND and
AGND wired together, unless otherwise noted.
Note 3:
When the analog input voltage is taken below ground it will be
clamped by an internal diode. This product can handle, with no external
diode, input currents of greater than 60mA below ground without latch-up.
Note 4:

CLK

LTC1272-8, t
r
= t
f
= 5ns unless otherwise specified. For best analog
performance, the LTC1272 clock should be synchronized to the RD and
CS control inputs with at least 40ns separating convert start from the
nearest clock edge.
Note 5:
Linearity error is specified between the actual end points of the
A/D transfer curve.
Note 6:
The LTC1272 has the same 0V to 5V input range as the AD7572
but, to achieve single supply operation, it provides a 2.42V reference
output instead of the –5.25V of the AD7572. This requires that the polarity
of the reference bypass capacitor be reversed when plugging an LTC1272
into an AD7572 socket.
Note 7:
Guaranteed by design, not subject to test.
Note 8:
V
DD
= 5V. Timing specifications are sample tested at 25
°
C to
ensure compliance. All input control signals are specified with t
r
= t
f
= 5ns
(10% to 90% of 5V) and timed from a voltage level of 1.6V. See Figures 13
through 17.
