NOTES: (1) Junction temperature = ambient temperature for low temperature limit and +25
°
C Test Level A specifications. Junction temperature = ambient
temperature +23
°
C at high temperature limit Test Level A specifications.
(2) Junction temperature = ambient at low temperature limit; junction temperature = ambient +1
°
C at high temperature limit for over-temperature
tested specifications.
(3) Test Levels: (A) 100% tested at +25
°
C. Over temperature limits by characterization and simulation. (B) Limits set by characterization and
simulation. (C) Typical value for information only.
(4) Current is considered positive out of node.
(5) CMIR tested as < 3dB degradation from minimum CMRR at specified limits.
(6) I
(V
bias current) is negative, and I
(V
bias current) is positive, under these conditions. See Note 3 and Figures 2 and 12.
(7) Limiter feedthrough is the ratio of the output magnitude to the sinewave added to V
(or V
) when V
= 0.
(8) V
slew rate conditions are: V
= V
+0.4V, G = +6, V
= V
–
1.2V, V
= step between V
+1.2V and V
. V
slew rate conditions are similar.
(9) Linearity Guardband is defined for an output sinusoid (f = 5MHz, V
= V
±
1V
) centered between the limiter levels (V
H
and V
L
). It is the
difference between the limiter level and the peak output voltage where SFDR decreases by 3dB (see Figure 8).
