Hi, I want to get a V input into an Arduino from a VEGA BAR14 pressure sensor which outputs mA. Yes I know I can convert to V. Texas Instruments RCV Linear – Amplifiers – Instrumentation, OP Amps, Buffer Amps parts available at DigiKey. You can make a single-supply current loop receiver with the RCV by using its 10V reference as a pseudo ground. The RCV will convert a mA loop.

Sep 9, 2: Interesting to play with though. Furthermore this product was released in the late 80’s, a time where logic levels and common supply voltages were much different than they often are now.

Since it is basically still a difference amplifier if you change the polarity of the input signal then the output signal will change polarity as well. Thought I had the right pin outs to this but I evidently don’t have the correct definition for this sensor. Ask a related question Ask a new question.

Jan 9, 2: Hello Friedrich, I moved your post to a new thread because it started a new topic regarding the fault protection discussed in SBVA Jan 24, 6: TI is a global semiconductor design and manufacturing company. The circuit you provided would not work well in production because IC6 uses rcvv420, instead of negative feedback for operation.

The problem is that I am getting an offset of about 1. The newly rvv420 question will be automatically linked to this question.

If you have a related question, please click the ” Ask a related question ” button in the top right corner. Please help me if I am using it correctly or what rcv40 do I need to make in order to null the offset and get 0 to 5 V corresponding to 4 to 20 mA Thanking you in anticipation.

First to be clear there are internal ESD diodes between the output and the supply voltage. Not sure why you think adding this chip would be better.

I moved your post to a new thread because it started a new topic regarding the fault protection discussed in SBVA In reply to John Westmoreland Colin, Thanks for the reply. This is an example. Quick question; I currently have 12 grounded and shorted.
