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 105dB.
