Features 741 op amp operating characteristics   Class AB output stage-no crossover distortion   Pin compatible with the LM124   Overload protection for inputs and outputs   Low supply current drain: 0.6 mA/Amplifier Low input offset voltage: 1 mV Low input offset current: 4 nA Low input bias current 30 nA High degree of isolation between amplifiers: 120 dB Gain bandwidth product   LM148 (unity gain): 1.0 MHz Description The LM148 series is a true quad 741. It consists of four independent, high gain, internally compensated, low power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar 741 operational amplifier. In addition the total supply current for all four amplifiers is comparable to the supply current of a single 741 type op amp. Other features include input offset currents and input bias current which are much less than those of a standard 741. Also, excellent isolation between amplifiers has been achieved by independently biasing each amplifier and using layout techniques which minimize thermal coupling. The LM148 can be used anywhere multiple 741 or 1558 type amplifiers are being used and in applications where amplifier matching or high packing density is required. For lower power refer to LF444.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
