Operational Amplifiers - National Semiconductor

The LM112 series LM112 LM212 LM312 are micropower Operational Amplifiers with very low offset-voltage and input-current errorsat least a factor of ten better than FET Amplifiers over a b55Cto a125C temperature range. Similar to the LM108 series, that also use supergain Transistors they differ in that they include internal frequency compensation and have pro- visions for offset adjustment with a single potentiometer. These Amplifiers will operate on supply voltages of g2V to g20V, drawing a quiescent current of only 300 mA. Per- formance is not appreciably affected over this range of volt- ages, so operation from unregulated power sources is easily accomplished. They CAN also be run from a single supply like the 5V used for digital circuits. The LM112 series are the first IC Amplifiers to improve reli- ability by including overvoltage protection for the MOS com- pensation capacitor. Without this feature, ICs have been known to suffer catastrophic failure caused by short-dura- tion overvoltage spikes on the supplies. Unlike other inter- nally-compensated IC Amplifiers it is possible to overcom- pensate with an external capacitor to increase stability mar- gin. The LM212 is identical to the LM112 except that the LM212 has its performance guaranteed over a b25Cto a85C temperature range instead of b55Cto a125C. The LM312 is guaranteed over a 0Cto a70C temperature range By National Semiconductor Corporation
