lm741 operational amplifier general description the lm741 series are general purpose operational amplifi- ers which feature improved performance over industry stan- dards like the lm709. they are direct, plug-in replacements for the 709c, lm201, mc1439 and 748 in most applications. 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. the lm741c is identical to the lm741/lm741a except that the lm741c has their performance guaranteed over a 0c to +70c temperature range, instead of ?55c to +125c. connection diagrams typical application metal can package ds009341-2 note 1: lm741h is available per jm38510/10101 order number lm741h, lm741h/883 (note 1) , lm741ah/883 or lm741ch see ns package number h08c dual-in-line or s.o. package ds009341-3 order number lm741j, lm741j/883, lm741cn see ns package number j08a, m08a or n08e ceramic flatpak ds009341-6 order number LM741W/883 see ns package number w10a offset nulling circuit ds009341-7 august 2000 lm741 operational amplifier ? 2000 national semiconductor corporation ds009341 www.national.com
