(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) 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 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

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