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.
