(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 T
J
= T
A
. No parametric performance is indicated in the electrical tables under conditions of
internal self-heating where T
J
> T
A
.
(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 A
VMAX
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

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