(1)

Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical

tables under conditions of internal self-heating where TJ > TA

(2)

For annotation brevity, “HP”=High Power, “MP”=Medium Power, “LP” =Low Power, “DIS”=Disabled or shut down, “SE”=Single Ended

Mode, “DM”=Differential Mode. See Table 1 in Applications section for power setting details. It is also assumed RG = RG1 = RG2

(3)

Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using the

Statistical Quality Control (SQC) method.

(4)

Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary

over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped

production material.

(5)

Drift Determined by dividing the change in parameter at temperature extremes by the total temperature change. Value is the worst case

of TaMIN to 25°C and 25°C to TaMAX.

(6)

At amplifier inputs.
