Boldface limits are tested at +25°C.
At T

= 402Ω, and R
L
= 100Ω, unless otherwise noted. See Figure 1 for AC performance only.
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. V
CM
is the input common-mode voltage.
(5) Tested < 3dB below minimum CMRR specifications at ±CMIR limits.
(6) Peak output duration should not exceed junction temperature +150°C for extended periods.
(7) Not connecting the exposed slug to the –V
J
plane gives 75°C/W thermal impedance ( θ
