Opam question

So it doesn't short out? Op amps have low output impedance.

RL is short for *load resistor*. Loads ( if required ) do indeed normally connect at the output !

They are rarely necessary though. You should post a schematic.

A clueless answer from a Google groups user to a clueless question from another Google groups user !

No surprise there I guess ?

Graham

In series with the output or to ground?

A series resistor might be inserted to reduce output current.

A 1K resistor to ground on the output of an LM324 op-amp reduces crossover distortion, by biasing the output stage into class A.

Hi,

With respect to the ground, yes RL stands for Load resistor. How can a load resistor help in not shorting the OPAM, here a series resistor can do!!

In the fashion below: -----|\\ | /--- -----|/ _|_ |RL| ------ | ----- GND

Thanks and regards,

Nick

Very often, sample circuits will show an "Rl" like that, just to show how the load should be connected. In Real Life, you would rarely put a resistor there - you connect your load, whatever it may be, in place of Rl.
