3.3V Electrical Characteristics

(1) (continued)

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.

(11) 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

5V Electrical Characteristics

(1)

The electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as otherwise

modified or specified by the Electrical Characteristics Conditions and/or Notes. 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.
