When designing high performance systems for RF and video applications requiring amplifiers, multiplexers, or programmable gain amplifiers, finding the right components to do the job is not simple. A pair of SWOP amps from Burr- Brown, the OPA675 and OPA676, open the door to high speed without the headaches. These devices are true operational amplifiers with a built-in switchable front end, hence the name SWOP amp, for switchable input OP amp. The resulting integrated circuit functions as a fast settling wideband op amp with a DPDT switch on the two input pins. Using a SWOP amp makes it easy to switch from one channel to another in nanoseconds.
