It consists of 2 • 741 Op Amp Operating Characteristics four independent, high gain, internally compensated, • Class AB Output Stage—No Crossover low power operational amplifiers which have been Distortion designed to provide functional characteristics • Pin Compatible With the LM124 identical to those of the familiar 741 operational amplifier. In addition the total supply current for all • Overload Protection for Inputs and Outputs four amplifiers is comparable to the supply current of • Low Supply Current Drain: 0.6 mA/Amplifier a single 741 type op amp. Other features include • Low Input Offset Voltage: 1 mV input offset currents and input bias current which are much less than those of a standard 741. Also, • Low Input Offset Current: 4 nA excellent isolation between amplifiers has been • Low Input Bias Current 30 nA achieved by independently biasing each amplifier and • High Degree of Isolation Between Amplifiers: using layout techniques which minimize thermal 120 dB coupling. • Gain Bandwidth Product The LM148 can be used anywhere multiple 741 or – LM148 (Unity Gain): 1.0 MHz 1558 type amplifiers are being used and in applications where amplifier matching or high packing density is required. For lower power refer to LF444.
