Operational Amplifier, Low
Voltage
NCV5230
The NCV5230 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 A when the current
