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.

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.

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).
