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 voltage values are with respect to ground with DGND and
AGND wired together (unless otherwise noted).
Note 3: When these pin voltages are taken below V
LTC1273) or above V
product can handle input currents greater than 60mA below V
for LTC1273) or above V
Note 4: When these pin voltages are taken below V
LTC1273) they will be clamped by internal diodes. This product can handle
input currents greater than 60mA below V
without latch-up. These pins are not clamped to V

denotes the specifications which apply over the full operating temperature
Note 6: Linearity, offset and full scale specifications apply for unipolar and
bipolar modes.
Note 7: Integral nonlinearity is defined as the deviation of a code from a
straight line passing through the actual endpoints of the transfer curve.
The deviation is measured from the center of the quantization band.
Note 8: Bipolar offset (LTC1275/LTC1276) is the different voltage
measured from – 0.5LSB when the LTC1275/LTC1276 output code flickers
between 0000 0000 0000 and 1111 1111 1111.
Note 9: Guaranteed by design, not subject to test.
Note 10: Recommended operating conditions.
Note11: A
specified accuracy. Therefore the minimum supply voltage for the
LTC1273 is + 4.95V. The minimum supplies for the LTC1275 are +4.75V
and – 2.45V and the minimum supplies for the LTC1276 are ±4.95V.
