TYP
MIN/MAX OVER TEMPERATURE
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) IVH (VH bias current) is positive, and IVL (VL 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 VH (or VL) when VIN = 0.
ELECTRICAL CHARACTERISTICS: VS = ±5V
Boldface limits are tested at +25
°C.
G = +6, RF = 750Ω, RL = 500Ω, and VH = –VL = 2V, (see Figure 1 for AC performance only), unless otherwise noted.
