analog mv switch for digital meters
This circuit utilizes a 4052 as a DC Analog Multiplexer. The inputs to this multiplexer must originate from low-impedance output operational amplifiers (OpAmps). The resistors depicted are unnecessary once the signal conditioning OpAmps are connected. However, 100K resistors can be...
Robots Bandpass Filter Calculator
These are operational amplifier (op-amp) based filters that are particularly effective within the audio frequency range. The calculators for these filters utilize formulas and tables from the book "Electronic Filter Design Handbook" by Arthur B. Williams. Bandpass filters allow a...
Op-Amp-Based Wien Bridge Oscillator
The circuit was designed based on the functionality of an operational amplifier to create a Wien bridge oscillator that generates sine waves in the frequency range of 15 Hz.
The Wien bridge oscillator is a type of electronic oscillator that produces...
Doppler Rdf
The power supply consists of a 7812 voltage regulator followed by an operational amplifier (op-amp) configured to output 6V, which serves as a midpoint supply voltage for the audio op-amp stages. A 12V regulator is deemed excessive for battery-powered applications....
Amplifier Timer Circuit
This circuit turns off an amplifier or any other device when a low-level audio signal fed to its input is absent for at least 15 minutes. By pressing P1, the device is powered on, supplying power to any appliance connected...
Linear-ic-siren
A low-frequency op-amp oscillator and a voltage-controlled oscillator (VCO), both configured using a single MC3405 dual op-amp and dual comparator, are the primary components in a siren circuit capable of producing various warbles and wails, or functioning as an audio...
Multiple-feedback bandpass filter
The operational amplifier (op amp) is configured in inverting mode. Resistor R3 connects the output to the inverting input, establishing the gain and the current through the frequency-determining capacitor, C1. Capacitor C2 provides feedback from the output to the junction...
Op-Amp Colpitts Oscillator
A Colpitts oscillator can be implemented using an operational amplifier, provided that the op-amp has an appropriate bandwidth. An example of such a circuit can utilize the LT1190 or LT1191.
The Colpitts oscillator is a type of electronic oscillator that generates...
Automatic mooring light
The integrated circuit U1, which can be an LF351 or a 741 operational amplifier, functions as a comparator to regulate lighting. Resistors R2 and R3 establish a reference voltage of approximately 2.5 volts at pin 3 of U1. When light...
