(2) Junction temperature = ambient at low temperature limits; junction temperature = ambient +5°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. Copyright © 2005–2008, Texas Instruments Incorporated Submit Documentation Feedback 7 Product Folder Link(s): OPA2832 |
