Where to Use LF351 IC?

LF351 is single operational amplifier with an internally compensated input offset voltage. It also provides wide bandwidth, low input bias current and offset current. Basically, LF351 is used in the circuits that need high input impedance, high speed integrators, Quick digital to analog converters, sample and hold circuits etc.

 

How to Use the IC?

The below circuit diagram is used to generate the square wave, by adding few resistor and capacitor externally. It is like a Schmitt trigger circuit that the reference voltage for the comparator action depends on the output voltage. For finding the value of the output frequency use the formula mentioned below:

FOSC = 1 / 2RFCF
