Re: 78L05

yeah i habe a 0.1uF cap on the output. I have just read 2 different 78L05 data sheet and they both have different input caps. The national semiconductors sheet says use a 0.33uF cap.<p>Which way would you guys go, up or down? Or just plug and play and see what happens?<p>Cheers Turbo46

Re: Offset voltage on voltage follower

Back again<p>Circuit requirements:<p>*input to op-amp = 0 to 5v, from instrument
*output from op-amp = 0.5v to 3.5v, to transducer<p>This is in relation to my above post.<p>cheers.

Re: Offset voltage on voltage follower

Hi again<p>The 100k is the transducer, and 10k is the instrument. When i first built the circuit i put 1k in to test it. Then i was going to put a 100k in, but i didnt have one available.<p>Sorry to muck you around.<p>Thanks again.
