1 µa71, µa71y Short-Circuit Protection Offset-Voltage Null Capability Large Common-Mode and Differential Voltage Ranges No Frequency Compensation Required Low Power Consumption No Latch-Up Designed to Be Interchangeable With Fairchild µa71 SLOS9B NOVEMBER 197 REVISED SEPTEMBER 2 OFFSET N1 IN IN+ V CC µa71m...j PACKAGE (TOP VIEW) V CC + OUT OFFSET N2 description symbol The µa71 is a general-purpose operational amplifier featuring offset-voltage null capability. The high common-mode input voltage range and the absence of latch-up make the amplifier ideal for voltage-follower applications. The device is short-circuit protected and the internal frequency compensation ensures stability without external components. A low value potentiometer may be connected between the offset null inputs to null out the offset voltage as shown in Figure 2. The µa71c is characterized for operation from C to 7 C. The µa71i is characterized for operation from C to 5 C.The µa71m is characterized for operation over the full military temperature range of 55 C to 125 C. OFFSET N1 µa71m...jg PACKAGE µa71c, µa71i...

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC. 2. Differential voltages are at IN+ with respect to IN. 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.. The output may be shorted to ground or either power supply.
