Over temperature limits by characterization and simulation. (B) Limits set by characterization and simulation. (C) Typical value only for information. (2) Junction temperature = ambient for 25 °C guaranteed specifications. (3) Junction temperature = ambient at low temperature limit: junction temperature = ambient +23 °C at high temperature limit for over temperature guaranteed specifications. (4) Current is considered positive out-of-node. VCM is the input common-mode voltage. (5) Tested < 3dB below minimum specified CMR at ±CMIR limits. |
