OPA681N BURR-BROWN [Burr-Brown Corporation], OPA681N Datasheet - Page 2

• Manufacturer Part Number: OPA681N
• Description: Wideband, Current Feedback OPERATIONAL AMPLIFIER With Disable
• Manufacturer: BURR-BROWN [Burr-Brown Corporation]

SPECIFICATIONS: V
R
NOTES: (1) 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. (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.
