NTE725
Integrated Circuit
Dual Low Noise Preamp/OP Amp
Description:
The NTE725 consists of two identical high鈥揼ain operational amplifiers constructed on a single chip.
These 3鈥搒tage amplifiers use Class A PNP transistor output stages with uncommitted collectors. This
enables a variety of loads to be employed for general purpose applications from DC to 10MHz, where
two high performance operation amplifiers are required. In addition, the outputs may be wired鈥揙R
for use as a dual comparator or they may function as diodes in low thershold rectifying circuits such
as absolute value amplifiers, peak detectors, etc.
