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, AGND,
GND and REF
–
wired together (unless otherwise noted). REF
–
is internally
connected to the AGND pin on the LTC1093. DGND, AGND, REF
–
and V
–
are internally connected to the GND pin on the LTC1091/LTC1092.

–
= 0V for unipolar mode and
–5V for bipolar mode, CLK = 0.5MHz unless otherwise specified.
Note 4:
These specs apply for both unipolar (LTC1091/LTC1092/LTC1093/
LTC1094) and bipolar (LTC1093/LTC1094 only) modes. In bipolar mode,
one LSB is equal to the bipolar input span (2V
REF
) divided by 1024. For
example, when V
REF
= 5V, 1LSB (bipolar) = 2(5V)/1024 = 9.77mV.
Note 5:
Linearity error is specified between the actual end points of the
A/D transfer curve.
Note 6:
Total unadjusted error includes offset, full scale, linearity,
multiplexer and hold step errors.
Note 7:
Two on-chip diodes are tied to each reference and analog input
which will conduct for reference or analog input voltages one diode drop
below V
–
or one diode drop above V
CC
. Be careful during testing at low
V
CC
levels (4.5V), as high level reference or analog inputs (5V) can cause
this input diode to conduct, especially at elevated temperatures, and cause
errors for inputs near full scale. This spec allows 50mV forward bias of
either diode. This means that as long as the reference or analog input does
not exceed the supply voltage by more than 50mV, the output code will be
correct. To achieve an absolute 0V to 5V input voltage range will therefore
require a minimum supply voltage of 4.950V over initial tolerance,
temperature variations and loading.
Note 8:
Channel leakage current is measured after the channel selection.
