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
connected to the AGND pin on the LTC1093. DGND, AGND, REF
are internally connected to the GND pin on the LTC1091/LTC1092.

– 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

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.
