uA747C, uA747M DUAL GENERAL-PURPOSE OPERATIONAL AMPLIFIERS SLOS009A – D971, FEBRUARY 1971 – REVISED OCTOBER 1990 • • • • • • • No Frequency Compensation Required Low Power Consumption Short-Circuit Protection Offset-Voltage Null Capability Wide Common-Mode and Differential Voltage Ranges No Latch-Up Designed to Be Interchangeable With Fairchild µA747C and µA747M D, J, N, OR W PACKAGE (TOP VIEW) IN – IN + OFFSET 1N2 VCC – OFFSET 2N2 IN + IN – 1 2 3 4 5 6 7 14 13 12 11 10 9 8 OFFSET 1N1 1 VCC +† OUT NC OUT 2 VCC +† OFFSET 2N1 description The uA747 is a dual general-purpose operational amplifier featuring offset-voltage null capability. Each half is electrically similar to uA741. The high common-mode input voltage range and the absence of latch-up make this 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 uA747C is characterized for operation from 0°C to 70°C; the uA747M is characterized for operation over the full military temperature range of – 55°C to 125°C. uA747m . . .

Differential voltages are at the noninverting input terminal with respect to the inverting input terminal. 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. For the uA747M only, the unlimited duration of the short circuit applies at (or below) 125°C case temperature or 75°...
