The LM series are general purpose operational amplifi- ers which feature improved performance over industry stan- dards like the LM The amplifiers offer many features which make their applica- tion nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is ex- ceeded, as well as freedom from oscillations.
