I'm feeding the amplified output to an Arduino and using an external interrupt to find the falling/rising edge. But I'm getting bouncing on the edge as there is noise in the amplified signal.

Web13 de jan. de 2015 · The op amp inputs have high impedance, so that "no" current flows through the switch. The switch does carry the op-amp's bias/offset currents. If you want to compensate for it, leave the SW3 from the same package in series with the positive input. That switch will be closed at all times. If the op-amp has very low offset current, you can … Web403K views 5 years ago Op-Amp (Operational Amplifier) In this video, op-amp differentiator circuit has been discussed (with derivation) and few examples have been solved based on this...

Web4 Choosing the Op Amp. Size and number of channels: The op amp chosen is typically a single channel op amp as only one is required. Texas Instruments offers-single channel op amps in SOT-23, MSOP 8-pin, and SOIC 8-pin packages. Rail-to-rail input or output: The input signal to the op amp is the sense voltage (Vsense), which is ground referenced. WebAn operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output. Op amps usually have three terminals: two high-impedance inputs and a low-impedance output port. The inverting input is denoted with a minus (-) sign, and the non-inverting input uses a positive (+) sign.
