ELECTRICAL CHARACTERISTICS: VS = +5V
Boldface limits are tested at +25
°C.
At RF = 402Ω, RL = 100Ω to VS/2, and G = +2 (see Figure 2 for AC performance only), unless otherwise noted.

(1)
Junction temperature = ambient for +25
°C specifications.
(2)
Junction temperature = ambient at low temperature limits; junction temperature = ambient +15
°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. VCM is the input common-mode voltage.
(5)
Tested < 3dB below minimum specified CMRR at
± CMIR limits.
