(2) Typical values represent the most likely parameter norms at TA = 25°C, and at the Recommended Operation Conditions at the time of product characterization.
(3) Slew rate is the average of the rising and falling slew rates.
(4) Offset voltage drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
(5) AC common-mode signal is a 5-VPP sine-wave (0 V to 5 V) at the given frequency.
(6) Positive current corresponds to current flowing into the device.
(7) For this test input is driven from A1 stage.
(8) For VOL, RL is connected to VS and for VOH, RL is connected to GND.
(9) Short-Circuit test is a momentary test. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C.
(10) Both the gain of preamplifier K1 and the gain of buffer amplifier K2 are measured individually. The overall gain of both amplifiers (AV) is also measured to assure the gain of all parts is always within the AV limits.
