Over temperature limits set by characterization and simulation. (B) Limits set by characterization and simulation. (C) Typical value only for information. (2) Junction temperature = ambient for +25 °C tested specifications. (3) Junction temperature = ambient at low temperature limit; junction temperature = ambient +2 °C at high temperature limit for over temperature specifications. (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 3 Submit Documentation Feedback |
