DESCRIPTION

The OPA2650 is a dual, low power, wideband voltage
feedback operational amplifier. It features a high band­width of 360MHz as well as a 12-bit settling time of
only 20ns. The low distortion allows its use in commu­nications applications, while the wide bandwidth and
true differential input stage make it suitable for use in
a variety of active filter applications. Its low distortion
gives exceptional performance for telecommunica­tions, medical imaging and video applications.

The OPA2650 is internally compensated for unity­gain stability. This amplifier has a fully symmetrical
differential input due to its “classical” operational
amplifier circuit architecture. 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.

The OPA2650 is also available in single (OPA650)
and quad (OPA4650) 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.

ELECTROSTATIC
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.
