IC LM741 as a Signal Generator: The operational amplifier IC-741 is not only instrumentation amplifier, it can generate different type of the waveforms by charging and discharging mode. Function generator give waveforms such as sine, triangular, square waves and so on of different frequencies and amplitudes. Here
An operational Amplifier IC LM741 used as a voltage to current. It is used for signal transmission of instrumentation like RTD THEROCOUPLE single from long distance to control circuits. Two type of current converter are., Floating load Voltage to Current converter. Ground load Voltage to Current converter.
Voltage Comparator circuit:- A fixed reference voltage Vref is applied to the (-) input, and the other time – varying signal voltage Vin is applied to the (+) input; Because of this arrangement, the circuit is called the non-inverting comparator. Depending upon the levels of Vin and Vref, the circuit produces output. In short,
The adder can be obtained by using either non-inverting mode or differential amplifier. Here the inverting mode is used. So the inputs are applied through resistors to the inverting terminal and non-inverting terminal is grounded. This is called “virtual ground”, i.e. the voltage at that
The IC 741 is a high performance monolithic operational amplifier constructed using the instrumentation process. High common mode voltage range and absence of latch-up tendencies make the IC 741 ideal for use as voltage follower. The high gain and wide range of operating voltage provide superior performance in integrator, summing
INTEGRATOR:– An integrator circuit integrates the input signal with respect to time (Frequency). The circuit diagram of integrator, the feedback element is capacitor (0.047) and input element is (10k) resistor. IMPORTANT:- Select input square wave from 500 Hz to 1.5 KHz to get correct output triangle wave. Otherwise change the capacitor value. The charge on
