INTEGRATED CIRCUITS NE/SA5230 Low voltage operational amplifier Product specification 1994 Aug 31 Philips Semiconductors Philips Semiconductors Product specification Low voltage operational amplifier NE/SA5230 DESCRIPTION PIN CONFIGURATION The NE5230 is a very low voltage operational amplifier that can N, D, FE Packages 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 1 8 NC swing to ground when applying the latter. There is a bias adjusting NC pin which controls the supply current required by the device and 2 7 –IN V – CC thereby controls its power consumption. If the part is operated at + 3 6 +IN OUTPUT ±0.9V supply voltages, the current required is only 110µA when the curren
