and simulation. (C) Typical value only for information.
(2) Junction temperature = ambient for +25 ° C specifications.
(3) Junction temperature = ambient at low temperature limits; junction temperature = ambient +48 ° C at high temperature limit for over
temperature specifications.
(4) Current is considered positive out of pin.
(5) Tested < 3dB below minimum specified CMRR at ± CMIR limits.
