(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 ensured specification of 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. Bold numbers refer to over temperature limits.
(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<30MHz, here are the Flat Band Attenuation
ranges:±0.2dB: 10V/V down to 1V/V=20dB range±0.1dB: 10V/V down to 4.7V/V=6.5dB range

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