(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. |
