(2) Junction temperature = ambient at low temperature limit: 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. |
