THERMAL CHARACTERISTICS
Temperature Range Specification: I
–40 to +85 °C typ C
Thermal Resistance Junction-to-Ambient
DSO-8 125 ———°C/W typ C
NOTES: (1) Junction temperature = ambient for +25°C specifications.
(2) Junction temperature = ambient at low temperature limit; junction temperature = ambient +23°C at high temperature limit for over temperature
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 only for information.
(4) Current is considered positive out of node.
(5) CMIR tested as < 3dB degradation from minimum CMRR at specified limits.
(6) I
VH
(V
H
bias current) is positive, and I
VL
(V
L
bias current) is negative, under these conditions. See Note 3, Figure 1, and Figure 8.
(7) Limiter feedthrough is the ratio of the output magnitude to the sinewave added to V
H
(or V
L
) when V
IN
= 0.
(8) V

slew rate conditions are: V
IN
= +2V, G = +2, V
L
= –2V, V
H
= step between 2V and 0V. V
L
slew rate conditions are similar.
(9) Linearity Guardband is defined for an output sinusoid (f = 5MHz, V

) centered between the limiter levels (V
H
and V

). It is the difference
between the limiter level and the peak output voltage where SFDR decreases by 3dB (see Figure 9).
