NE5230, SA5230, SE5230

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

common−mode 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

internally−compensated to reduce external component count.

The NE5230 has a low input bias current of typically 40 nA, and a

large open−loop gain of 125 dB. These two specifications are

beneficial when using the device in transducer applications. The large

open−loop gain gives very accurate signal processing because of the

large “excess” loop gain in a closed−loop system.

OUTPUT

BIAS ADJ.

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.
