  1. 1. LF153 LF253 - LF353 ® WIDE BANDWIDTH DUAL J-FET OPERATIONAL AMPLIFIERS . . . . . . . . LOW POWER CONSUMPTION WIDE COMMON-MODE (UP TO VCC+) AND DIFFERENTIAL VOLTAGE RANGE LOW INPUT BIAS AND OFFSET CURRENT OUTPUT SHORT-CIRCUIT PROTECTION HIGH INPUT IMPEDANCE J–FET INPUT STAGE INTERNAL FREQUENCY COMPENSATION LATCH UP FREE OPERATION HIGH SLEW RATE : 16V/µs (typ) N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) DESCRIPTION The LF353 are high speed J–FET input dual operational amplifiers incorporating well matched, high voltageJ–FET andbipolartransistorsin a monolithicintegrated circuit. The devicesfeaturehigh slew rates, low input bias and 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 exceeded.
