Part Details:

LM148LM248LM348 FOUR UA741 QUAD BIPOLAR OPERATIONAL AMPLIFIERS s LOW SUPPLY CURRENT: 0.53mA/AMPLI- FIER s CLASS AB OUTPUT STAGE: NO CROSS OVER DISTORTION s PIN COMPATIBLE WITH LM124s LOW INPUT OFFSET VOLTAGE: 1mVs LOW INPUT OFFSET CURRENT: 2nA N s LOW INPUT BIAS CURRENT: 30nA DIP14 (Plastic Package) s GAIN BANDWIDTH PRODUCT: 1.3MHzs HIGH DEGREE OF ISOLATION BETWEEN AMPLIFIERS: 120dB s OVERLOAD PROTECTION FOR INPUTS AND OUTPUTS DESCRIPTION The LM148 consists of four independent, high D gain internally compensated, low power opera- SO14 tional amplifiers which have been designed to pro- (Plastic Micropackage) vide functional characteristics identical to those ofthe familiar UA741 operational amplifier. In addi-tion the total supply current for all four amplifiers iscompatible to the supply current of a single UA741 PIN CONNECTIONS (top view) type op amp. Other features include input offsetcurrent and input bias current which are much lessthan those of a standard UA741. Also, excellentisolation between amplifiers has been achieved byindependently biasing each amplifier and usinglayout techniques qhich minimize thermal cou-pling.
