link to page 15 link to page 15 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 mA when the current 8 control pin is left open. Even with this low power consumption, the 1 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 NCV5230 also has a unique input stage that allows the
