NOTE: (1) Making use of all four power supply pins is highly recommended,

although not required. Using these four pins, instead of just pins 4 and 7, will

lower the power supply impedance improving distortion.

NOTES: (1) For detailed drawing and dimension table, please see end of data sheet, or Appendix C of Burr-Brown IC Data Book. (2) The “B” grade of the SO-8 and

DIP packages will be marked with a “B” by pin 8. The “B” grade of the SOT23-5 will be marked with a “B” near pins 3 and 4. (3) The SOT23-5 is only available on a 7"

tape and reel (e.g. ordering 250 pieces of “OPA643N-250” will get a single 250 piece tape and reel. Ordering 3000 pieces of “OPA643N-3k” will get a single 3000 piece

tape and reel). Please refer to Appendix B of Burr-Brown IC Data Book for detailed Tape and Reel Mechanical information.

PACKAGE/ORDERING INFORMATION

ELECTROSTATIC

DISCHARGE SENSITIVITY

Electrostatic discharge can cause damage ranging from per-

formance degradation to complete device failure. Burr-Brown

Corporation recommends that all integrated circuits be handled

and stored using appropriate ESD protection methods.

ESD damage can range from subtle performance degradation

to complete device failure. Precision integrated circuits may

be more susceptible to damage because very small parametric

changes could cause the device not to meet published speci-

fications.
