DESCRIPTION

These circuits are high speed J–FET input single operationalamplifiers incorporatingwell matched,high voltage J–FET and bipolar transistors in a monolithic integrated circuit. The devicesfeaturehigh slew rates, low input biasand offset currents, and low offset voltage temperature coefficient.

All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference level is the midpoint between VCC + and VCC –. 2. Differential voltages are at the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less. 4. The output may be shorted to ground or to either supply. Temperature and /or supply voltages must be limited to ensure that the dissipation rating is not excee ded.
