Low Voltage Operational
Amplifier
The NE5230 is a very low voltage operational amplifier that can
perform with a voltage supply as low as 1.8 V or as high as 15 V.
In addition, split or single supplies can be used, and the output will
swing to ground when applying the latter. There is a bias adjusting pin
which controls the supply current required by the device and thereby
controls its power consumption. If the part is operated at ±0.9 V
supply voltages, the current required is only 110 mA when the current
control pin is left open. Even with this low power consumption, the
device obtains a typical unity gain bandwidth of 250 kHz. When the
bias adjusting pin is connected to the negative supply, the unity gain
bandwidth is typically 600 kHz while the supply current is increased
to 600 mA. In this mode, the part will supply full power output beyond
the audio range.
The NE5230 also has a unique input stage that allows the
commonmode input range to go above the positive and below the
negative supply voltages by 250 mV. This provides for the largest
possible input voltages for low voltage applications. The part is also
internallycompensated to reduce external component count.
The NE5230 has a low input bias current of typically ±40 nA, and a
large openloop gain of 125 dB. These two specifications are
beneficial when using the device in transducer applications. The large
openloop gain gives very accurate signal processing because of the
large “excess” loop gain in a closedloop system.
The output stage is a class AB type that can swing to within 100 mV
of the supply voltages for the largest dynamic range that is needed in
many applications. The NE5230 is ideal for portable audio equipment
and remote transducers because of its low power consumption, unity
gain bandwidth, and 30 nV/Hz noise specification.
