Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the device should not be beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified. (2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJ(MAX), θJA, and the ambient temperature, TA. The maximum allowable power dissipation PDMAX = (TJ(MAX) - TA) / θJA or the number given in Absolute Maximum Ratings, whichever is lower. 3.3V Electrical Characteristics (1) Unless otherwise specified, all limits ensured at TA = 25°C, VS = 3.3V, GND = 0V, −4V ≤ VCM ≤ 27V, and RL = ∞, Offset (Pin 7) is grounded, 10nF between VS and GND. Boldface limits apply at the temperature extremes.

Typical specifications are estimations only and are not ensured. (2) Datasheet min/max specification limits are ensured by test. (3) Typical values represent the most likely parameter norms at TA = +25°C, and at the Recommended Operation Conditions at the time of product characterization and are not ensured. (4) Both the gain of the preamplifier A1V and the gain of the buffer amplifier A2V are measured individually. The over all gain of both amplifiers AV is also measured to assure the gain of all parts is always within the AV limits. (5) Slew rate is the average of the rising and falling slew rates. (6) Offset voltage drift determined by dividing the change in VOS at temperature extremes into the total temperature change. (7) AC Common Mode Signal is a 5VPP sine-wave (0V to 5V) at the given frequency.
