5V Electrical Characteristics(1) (continued)
Unless otherwise specified, all limits ensured for at TA = 25°C, VS = 5V, GND = 0V, −22V ≤ VCM ≤ 60V, and RL = ∞, Offset
(Pin 7) is grounded, 10nF between VS and GND. Boldface limits apply at the temperature extremes.

(7) AC Common Mode Signal is a 5VPP sine-wave (0V to 5V) at the given frequency.
(8) 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.
(9) Positive current corresponds to current flowing into the device.
(10) For this test input is driven from A1 stage in uni-directional mode (Offset pin connected to GND).
(11) For VOL, RL is connected to VS and for VOH, RL is connected to GND.
(12) 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.
