(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 parametric performance is indicated in the electrical tables under conditions of

internal self-heating where TJ > TA.

(2)

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 on shipped production material.

(3)

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

flatness specified (either ±0.2dB or ±0.1dB), 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.
