(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 ensurance 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 20dB down to 4dB = 16dB range
±0.1dB 20dB down to 12.5 dB = 7.5dB range
