description
The uA748 is a general-purpose operational amplifier that offers the same advantages and attractive features as the uA741 except for internal compensation. External compensation can be as simple as a 30-pF capacitor for unity-gain conditions and, when the closed-loop gain is greater than one, can be changed to obtain wider bandwidth or higher slew rate. This circuit features high gain, large differential and common-mode input voltage range, and output short-circuit protection. Input offset-voltage adjustment can be provided by connecting a variable resistor between the offset null pins as shown in Figure 12. The uA748C is characterized for operation from 0°C to 70°C; the uA748M is characterized for operation over the full military temperature range of 55°C to 125°C.

All voltage values, unless otherwise noted, are with respect to the midpoint between VCC + and VCC . 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 15V, whichever is less. The output may be shorted to ground or either power supply. For the uA748M only, the unlimited duration of the short circuit applies at (or below) 125°C case temperature or 75°C free-air temperature DISSIPATION RATING TABLE PACKAGE D JG P U TA 25°C POWER RATING 500 mW 500 mW 500 mW 500 mW DERATING FACTOR 5.8 mW/°C 8.4 mW/°C N/A 5.4 mW/°C DERATE ABOVE TA 64°C 90°C N/A 57°C TA = 70°C POWER RATING 464 mW 500 mW 500 mW 432 mW TA = 125°C POWER RATING N/A 210 mW N/A 135 mW

All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified. Full range for uA748C is 0°C to 70°C and for uA748M is 55°C to 125°C. NOTE 5: This typical value applies only at frequencies above a few hundred hertz because of the effects of drift and thermal feedback.
