The OPA678 is a wideband monolithic operational
amplifier with two independent differential inputs.
Either input can be selected by an external TTL or
ECL logic signal. The amplifier is externally compensated
and features a very fast input selection speed, 4ns
for either ECL or TTL. This amplifier features fully
symmetrical differential inputs due to its “classical”
operational amplifier circuit architecture. Unlike “current-
feedback” amplifier designs, the OPA678 may be
used in all op amp applications requiring high speed
and precision.
Low distortion and crosstalk make this amplifier suitable
for RF and video applications.
The OPA678 is available in plastic DIP and SO-16
packages.
