For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application

report, SPRA953.

(2)

The maximum power dissipation must be derated at elevated temperatures and is dictated by TJ(MAX), RθJA, and the ambient

temperature, TA. The maximum allowable power dissipation PDMAX = (TJ(MAX) – TA) / RθJA or the number given in Absolute Maximum

Ratings, whichever is lower.

(1)

Data sheet min and max limits are specified by test.

(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)

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.

(4)

Slew rate is the average of the rising and falling slew rates.

(5)

Offset voltage drift determined by dividing the change in VOS at temperature extremes into the total temperature change.

6.6 Electrical Characteristics: VS = 3.3 V

at TA = 25°C, VS = 3.3 V, GND = 0 V, –4 V ≤ VCM ≤ 27 V, RL = ∞, OFFSET (pin 7) is grounded, and 10 nF between VS and

GND (unless otherwise noted)
