DESCRIPTION
The LF353 are high speed J–FET input dual oper- ational amplifiers incorporating well matched, high voltage J–FET and bipolar transistors in a mono- lithic integrated circuit. The devices feature high slew rates, low input bias and offset currents, and low offset voltage temper- ature coefficient.

SCHEMATIC DIAGRAM (each amplifier) ABSOLUTE MAXIMUM RATINGS Symbol Parameter LF153 LF253 LF353 Unit VCC Supply voltage - note1) 1. 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 ± 18 V Vi Input Voltage - note2) 2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less. ± 15 V Vid Differential Input Voltage - note3) 3. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. ± 30 V Ptot Power Dissipation 680 mW Output Short-circuit Duration - note4) 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 exceeded Infinite Toper Operating Free-air Temperature Range -55 to +125 -40 to +105 0 to +70 °C Tstg Storage Temperature Range -65 to +150 °C
