The R1 resistance adjusts the threshold voltage of the circuit. In the below circuitry, LM348 is configured by inverting the Schmitt trigger.It uses piezoelectric sensors that operate as shock sensor which is mounted on the door that we have to guard It operates as an anti-theft alarm in vehicles. The shock alarm circuitry is commonly used in vehicles and created through the use of LM358.Pin 7 is the output of the second amplifier.Pin 6 is the negative input of the second operational amplifier.Pin 5 is the positive inverting input of the second operational amplifier.Pin 3 is the positive or non-inverting input of the first operational amplifier.Pin 2 is the negative or inverting input of the first operational amplifier.Pin 1 is the output of operational amplifier one.

It comes with eight pinouts that is listed here.Its single supply volts are three to thirty volts and double supply volts are ☑.5V to ☑6V.It has two operational amplifiers in one packaging.It has a single supply that can operate two operational amplifiers.It comes with short circuit protection output.The operating temperature is about zero to seventy centigrade.
