OPA658
DESCRIPTION
The OPA658 is an ultra-wideband, low power current
feedback video operational amplifier featuring high
slew rate and low differential gain/phase error. The
current feedback design allows for superior large signal bandwidth, even at high gains. The low differential
gain/phase errors, wide bandwidth and low quiescent
current make the OPA658 a perfect choice for numerous video, imaging and communications applications.
The OPA658 is optimized for low gain operation and
is also available in dual (OPA2658) and quad
(OPA4658) configurations.

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
demonstration boards show low parasitic layouts for this part. Refer to the demonstration board layout for details. (3) Slew rate is rate of change from 10% to 90%
of output voltage step. (4) At G = +1, R
FB
= 560Ω for PDIP and 402Ω for SO-8. (5) This specification is PC board layout dependent.

DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from performance 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 specifications.

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 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 “OPA658N-250” will get a single 250 piece tape and reel. Ordering 3000 pieces of “OPA658N-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.
