They feature a factor-of-ten increase in speed over general-purpose devices without sacrificing dc performance. The high speed and fast settling time of these operational amplifiers make them useful in A/D converters, oscillators, active filters, sample-andhold circuits, and general-purpose amplifiers. The LM118 is characterized for operation from – 55°C to 125°C. The LM218 is characterized for operation from – 25°C to 85°C, and the LM318 is characterized for operation from 0°C to 70°C. 8 2 7 3 6 4 5 COMP2 VCC + OUT BAL /COMP3 FK PACKAGE (TOP VIEW) description NC IN – NC IN + NC 4 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 NC VCC + NC OUT NC NC VCC – NC BAL/COMP3 NC These operational amplifiers have internal unitygain frequency compensation. This considerably simplifies their application, since no external components are necessary for operation. However, unlike most internally compensated amplifiers, external frequency compensation may be added for optimum performance. For inverting applications, feed-forward compensation boosts the slew rate to over 150 V/µs and almost double the bandwidth. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed. Further, a single capacitor may be added to reduce the settling time for 0.1% error band to under 1 µs. 1 NC BAL/COMP1 NC COMP2 NC D D D NC – No internal connection symbol BAL/COMP1 COMP2 BAL/COMP3 IN + 1 8 5 3 + OUT IN – 2 – Pin numbers shown are for the D, JG, and P packages.

All voltage values, unless otherwise noted, are with respect to the midpoint between VCC + and VCC – . 2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less. 3. The inputs are shunted with two opposite-facing base-emitter diodes for overvoltage protection. Therefore, excessive current flows if a different input voltage in excess of approximately 1 V is applied between the inputs unless some limiting resistance is used. 4. The output can be shorted to ground or either power supply. For the LM118 and LM218 only, the unlimited duration of the short circuit applies at (or below) 85°C case temperature or 75°C free-air temperature.
