Opamp as buffer
WebAn opamp solution is more complex so it has more points of failure. A one-transistor solutions is simple, has less points of failure and is therefore more robust. only delivers … Web11 de ago. de 2006 · Having the opportunity, I did a lot of testing and experimenting with these Op Amps as buffers. The goal was to find the Op Amp that will (apropriately implemented) have: - best sound possible - the least DC offset possible (to avoid the use of coupling cap) - easiest implementation - ability to drive loads as low as 1K The winner is …

Web7 de jun. de 2003 · Honestly never used a opamp as a simple buffer (unity gain). A friend emailed me and said to install a resistor in the feedback loop equivilent to the output impedence of the circuit feeding the amp, although he didn't say what this circuit might require. (10K parallelled with 27K....somewhere around 7K? Or feedback resistor not …
Web22 de jul. de 2015 · Another opamp after a buffer follower could be a seperate line driver, where a dedicated opamp can offer benefits such as isolation (in the case of needing to drive a capacitive load), or protection from short circuit.
