Safe-opamp-circuit
In intrinsically safe applications, it is sometimes necessary to separate sections of circuitry using resistors that limit current under fault conditions. The circuit presented offers an accurate analog output with effectively zero output impedance, despite the presence of resistors in...
Sine-Wave/Square-Wave Converter
An operational amplifier (op amp) configured as a comparator generates a 10-V peak-to-peak square wave output with a 100-mV input signal, operating up to 15 kHz. Adjust resistor R5 to achieve symmetry in the square wave at low input levels.
The...
Basic-track-and-hold-sample-and-hold
Feedback operates similarly to a conventional operational amplifier (op-amp) voltage follower, providing 11 unity-gain, non-inverting outputs. This configuration also features a very high input impedance. The primary distinction between a track-and-hold and a sample-and-hold lies in the duration for which...
OpAmp based Voltage Translator Ciruit for ADC of Micro-controller
All naturally occurring phenomena such as sound, temperature, and pressure are analog in nature. To enable a microcontroller to read analog signals for the analog-to-digital conversion process using a built-in analog-to-digital converter (ADC), it is essential to condition the analog...
Digitally tuned low power active filter
This constant gain, constant Q, variable frequency filter provides simultaneous low-pass, bandpass, and high-pass outputs. With the specified component values, the center frequency will be 235 Hz for high logic inputs and 23.5 Hz for low logic inputs. The quality...
The Universal Linear Component
Operational amplifiers are the simplest and most effective means of executing a variety of linear functions, ranging from basic amplification to intricate analog computations.
Operational amplifiers (op-amps) are versatile components widely utilized in electronic circuits for various applications. These devices can...
op amp Op Amp based Colpitts oscillator
An op-amp based Colpitts oscillator in Multisim displays a "timestep too small" error when the run button is pressed. Despite extensive research and attempts to resolve the issue, the error persists. The design features a C-L-C pi circuit that is...
Active Low-Pass Rc Filter Circuit
The circuit presented has a cutoff frequency of approximately 1 kHz. The resistors R1, R2, and capacitors C1, C2 can be adjusted to achieve any desired frequency.
The circuit is designed as a filter, likely a low-pass or high-pass filter, where...
5-Pole Low-Pass Filter Circuit
The LTC1063 is a monolithic low-pass filter that provides exceptional DC and AC performance. It features both internal and external clock tunability, with cutoff frequencies reaching up to 50 kHz, a typical output DC offset of 1 mV, and a...
