描述 Description

DESCRIPTION
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 compen sated 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 “cur rent-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 suit able for RF and video applications. The OPA678 is available in plastic DIP and SO-16 packages.FEATURES
