DESCRIPTION
The NE5230 is a very low voltage operational amplifier that can perform with a voltage supply as low as 1.8V or as high as 15V. 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 ±0.9V supply voltages, the current required is only 110µA when the current control pin is left open. Even with this low power consumption, the device obtains a typical unity gain bandwidth of
180kHz. When the bias adjusting pin is connected to the negative supply, the unity gain bandwidth is typically 600kHz while the supply current is increased to 600µA. In this mode, the part will supply full power output beyond the audio range.
