Wideband, Low Power Voltage Feedback OPERATIONAL AMPLIFIER DESCRIPTION
The OPA651 is a low power, wideband voltage feed-
back operational amplifier. It features a bandwidth at
G = +2 of 470MHz as well as a 12-bit settling time of
only 16ns. The wide bandwidth and true differential
input stage make it suitable for use in a variety of
applications. Its low distortion gives exceptional per-
formance for telecommunications, medical imaging
and video applications.
The OPA651 is compensated for stability in gains of
two or more, differentiating it from the unity gain
stable OPA650. Its unusual combination of speed,
accuracy and low power make it an outstanding choice
for many portable, multi-channel and other high speed
applications, where power is at a premium.

NOTES: (1) An asterisk (*) specifies the same value as the grade to the left. (2) Frequency response can be strongly influenced by PC board parasitics. The OPA651
is nominally compensated assuming 2pF parasitic load. The demonstration boards show low parasitic layouts for the different package styles. 3

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.

NOTE: (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 package
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 OPA651N-250 will get a single 250 piece tape and reel. Ordering 3000 pieces of OPA651N-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.
