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_VH (V_H bias current) is positive, and I_VL (V_L bias current) is negative, under these conditions. See Note 3 and Figures 1 and 12.
(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_H slew rate conditions are: V_IN = +0.7V, G = +6, 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 = 1MHz, V_O = 2V_PP) 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).
