DSO8(Plastic Micropackage)DESCRIPTION

The LF353 are high speed J–FET input dual oper-ational amplifiers incorporating well matched, highvoltage J–FET and bipolar transistors in a mono-lithic integrated circuit.

The devices feature high slew rates, low input biasand offset currents, and low offset voltage temper-ature coefficient.

°C°C

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-.

The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

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 exceeded
