Opamp as buffer
Web15 de fev. de 2024 · Yes and no. The opamp would generally have better PSRR, a plain follower rarely makes it beyond about 50 dB. Mind you, it is easy to nullify that advantage if you proceed to use rail decoupling capacitors to pump power supply noise into a highish-impedance shared ground return. Some RC filtering can work wonders. Web7 de jun. de 2003 · Honestly never used a opamp as a simple buffer (unity gain).

The precision divider resistors determine the output voltage and the opamp isn't that critical.
WebThe operational amplifier voltage follower, also called an op-amp buffer, is an op-amp circuit that uses a bare wire to provide feedback to the inverting input. The op amp buffer is the simplest configuration for providing … Web30 de nov. de 2011 · Voltage follower using opamp Current buffer. Current buffer is a circuit that is used to transfer current from a low input impedance circuit to a circuit having high input impedance. The current buffer circuit connected in between the two circuits prevents the second circuit from loading the first circuit.
