    A741 General-Purpose Operational Amplifiers1 Features 3 Description

    The A741 device is a general-purpose operational1 Short-Circuit Protection

    amplifier featuring offset-voltage null capability. Offset-Voltage Null CapabilityThe high common-mode input voltage range and the Large Common-Mode and Differential Voltageabsence of latch-up make the amplifier ideal forRanges voltage-follower applications. The device is short-

    No Frequency Compensation Required circuit protected and the internal frequency No Latch-Up compensation ensures stability without external

    components. A low value potentiometer may beconnected between the offset null inputs to null out2 Applicationsthe offset voltage as shown in Figure 11.

    DVD Recorders and PlayersThe A741C device is characterized for operation Pro Audio Mixersfrom 0C to 70C. The A741M device (obsolete) ischaracterized for operation over the full militarytemperature range of 55C to 125C.

    (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratingsonly, and functional operation of the device at these or any other conditions beyond those indicated under Recommended OperatingConditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

    (2) All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC.(3) Differential voltages are at IN+ with respect to IN .(4) The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.(5) The output may be shor
