LF253 General Description


The LF353 are high speed JFET input dual opera- tional amplifiers incorporatingwell matched, high voltageJFETandbipolar transistorsin amonolithicin-tegrated circuit.

The devicesfeaturehigh slew rates, low inputbiasand offset currents, and low offset voltage temperature coefficient.

Symbol Parameter Value Unit
VCC Supply Voltage - (note 1) ±18 V
Vi Input Voltage - (note 3) ±15 V
Vid Differential Input Voltage - (note 2) ±30 V
Ptot Power Dissipation 680 mW
  Output Short-circuit Duration - (note 4) Infinite  
Toper Operating Free Air Temperature Range LF353
                                                              LF253
                                                              LF153
0to70
40 to 105
55 to 125
Tstg Storage Temperature Range 65 to 150

Notes : 1. All voltage values, except differential voltage, arewith 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 terminalwith 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.
