(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)

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.

(3)

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.

(4)

Flat Band Attenuation (Relative To Max Gain) Range Definition: Specified as the attenuation range from maximum which allows gain

flatness specified (either ±0.2 dB or ±0.1 dB), relative to AVMAX gain. For example, for f < 30 MHz, here are the Flat Band Attenuation

ranges:

±0.2 dB: 19.7 dB down to -6.3 dB = 26 dB range

±0.1 dB: 19.7 dB down to 10.2 dB = 9.5 dB range

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