CONCLUSION
The NE5230 is a versatile op amp in its own right. The part
was designed to give low voltage and low power operation
without the limitations of previously available amplifiers
that had a multitude of problems. The previous application
examples are unique to this amplifier and save the user
money by excluding various passive components that would
have been needed if not for the NE5230’s special input and
output stages.
The NE5230 has a combination of novel specifications
which allows the designer to implement it easily into
existing low−supply voltage designs and to enhance their
performance. It also offers the engineer the freedom to
achieve greater amplifier system design goals. The low input
referenced noise voltage eases the restrictions on designs
where S/N ratios are important. The wide full−power
bandwidth and output load handling capability allow it to fit
into portable audio applications. The truly ample open−loop
gain and low power consumption easily lend themselves to
the requirements of remote transducer applications. The
low, untrimmed typical offset voltage and low offset
currents help to reduce errors in signal processing designs.
The amplifier is well isolated from changes on the supply
lines by its typical power supply rejection ratio of 105 dB.
