- Yes, a dual op-amp is identical with two single op-amps, just with shared
- power pins. A dual may in fact be better, since the two amplifiers will
- be at exactly the same temperature. It may be possible to use this fact
- to reduce thermal drifts etc. - difficult to say without more info on the
- specific application.
