(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 ensurance of 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. 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 AVMAX 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
