Product Summary

The LM208AJ is a precision operational amplifier having specifications about a factor of ten better thanFET amplifiers over their operating temperature range. Inaddition to low input currents, the LM208AJ has extremelylow offset voltage, making it possible to eliminate offset adjustments,in most cases, and obtain performance approachingchopper stabilized amplifiers. Although the circuit is interchangeable with anduses the same compensation as the LM208AJ, an alternatecompensation scheme can be used to make it particularlyinsensitive to power supply noise and to make supply bypasscapacitors unnecessary.
