Precision Full-Wave Rectifier – Dual-Supply
https://www.electronics-lab.com/precision-full-wave-rectifier-dual-supply/
This is a dual-supply precision full-wave rectifier board that can turn alternating current (AC) signals into single polarity signals. The OPAMPs, U1A, and U1B, buffer the input signal and compensate for the voltage drops across D1 and D2 allowing for small signal inputs. This implementation functions with limited distortion for 20Vpp input signals at frequencies […]

TSV792 – High bandwidth (50MHz) Low offset (200µV) Rail-to-rail 5V Op amp
https://www.electronics-lab.com/tsv792-high-bandwidth-50mhz-low-offset-200%c2%b5v-rail-to-rail-5v-op-amp/
The TSV791 and TSV792 are single and dual 50 MHz-bandwidth unity-gain-stable amplifiers. The rail-to-rail input stage and the slew rate of 30 V/µs make the TSV791 and TSV792 ideal for low-side current measurement. The excellent accuracy provided by maximum input voltage of 200 µV allows amplifying accurately small-amplitude input signal. The TSV792 can operate from […]
OPAMP Monostable
https://www.electronics-lab.com/article/opamp-monostable/
Introduction As we have seen in previous tutorials, circuits can be categorized by the number of states that they can be stable. For example, in the op-amp multivibrator tutorial there were astable, monostable, and bistable versions of the circuit. This tutorial will focus on the monostable form of the circuit, specifically the implementation for an […]

OPAMP Multivibrator
https://www.electronics-lab.com/article/opamp-multivibrator/
Introduction This tutorial will focus on a configuration commonly known as the multivibrator and particularly on op-amps based circuits. Indeed, multivibrators can also be designed thanks to bipolar transistors or also timer integrated circuits such as NE555 but we will focus on OPAMP implementation. In its general definition, a multivibrator is an electronic oscillator that […]
