LT1013 Precision Dual Op-Amp IC Gearbox It is a general-purpose 3mmLT1013 is the first precision dual op amp in the 8 pin industry standard configuration, upgrading the performance of such popular devices as the MC1458 1558, LM158 and OP 221. The LT1013s Specification are similar to (even somewhat better than) the LT1014s. Both the LT1013 and LT1014 can be operated off a single power supply: input common mode range includes ground; the output can also swing to within a few millivolts of ground. Crossover distortion,
