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 鈥渃lassical鈥?/div>

operational amplifier circuit architecture. Unlike 鈥渃ur-

rent-feedback鈥?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.
