Here I have used it for the resistance measurement RL1. I am also running the op-amp circuit that you suggested sometime back.

LM347 comparator/op-amp

You also need to tell us what your load resistance is. Oct 16, 1.

In your schematic, R4 is shorted out, and does nothing, as I pointed out lm3477 my previous post. Instrumentation amplifier Posted by Blackbull in forum: Roff Well-Known Member Aug 24, Apr 14, 7, You have adviced to connect the capacitors in the power source terminals. Your input signal s must be connected to ground through some path. Welcome to our site! They worked for our purposes, and some dztasheet those applications called for precision performance.

Replacement Transformer Started by ncag 16 minutes ago Replies: It is the same.

For larger signals, ns is typical. I intend to use this IC as an instrumentation amplifier to amplify sensor signal. You found enough other references to convince me that one or more companies produced parts labeled LM Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Better Know a Hardware Description Language: They would have superior performance because the internal resistors are trimmed more accurately. Aug 21, 5, 1, It seem like discontinue item.

That should be enough to provide input bias current.

National Semiconductor

Rightnow I am not getting the linearity. You really don’t want to try to build an instrumentation amplifier using an opamp.

Oct 17, 4. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Oct 18, 8. Aug 17, 34 0. LM as instrumentation amplifier Posted by JehanKhan in forum: The response time specified is for a mV input step with 5.


Usally the zero is adjusted on the tranceducer and span is the gain adjustment of the instrumentationamplifier.

Till now I am measuring with DVM. Thread starter erictham83 Start date Aug 20, I have tied PS ground,reference terminal and input signal “0”. The datasheet page 14 – 18 deal with the input circuit and reference connection. Discussion in ‘ General Electronics Chat ‘ started by vijuOct 16, Forums New posts Search forums. I also tried connecting to “0” of input signal.

And we didn’t take the bus to school You May Also Like: Oct 17, 5. Viju, are you providing an input bias current return path? Yes, my password is: I have attached my complete schematic here. Oct 20, It looks like you have grounded the inverting input.
