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: Guaranteed by design and not subject to test.

Note 3: 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 4: Trimmed to an ideality factor of 1.004 at 25°C. Remote diode

temperature drift (TUE) verified at diode voltages corresponding to

the temperature extremes with the LTC2990 at 25°C. Remote diode

temperature drift (TUE) guaranteed by characterization over the LTC2990

operating temperature range.
