RCV420 PDF

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.

Thanks, useful to know. And there’s no VMax? To convert a mA signal to a V output a It says the min is 10V.

That will affect the necessary connections around the RCV We’re actually doing a board design review now; we have 4 RCV ‘s per board; so you know. What is the purpose of the two capacitors in fig 8?

Hi John, That was a simple mistake on my part. I think Fig 8. Thanks for your interest in the RCV Hello John, Thanks for the additional information. Jan 21, Thought I had the right pin outs to this but I evidently don’t have the correct definition for this sensor.

Also in this post you mentioned that the sensor output around mA, causing the RCV output to saturate to around Sep 11, 4: In reply to Ian Williams:.

Thanks Again, John W. I suppose we can put some clamping diodes on this so we don’t accidentally zap our host processors ADC port s.

Mentions Tags More Cancel. The over-range comparator is set 24mA and the rcv42 comparator is set at 2mA. Had hoped to learn something. Quick question; I rcv4200 have 12 grounded and shorted. Content on this site may contain or be subject to specific guidelines or limitations on use.

That said, there’s something wrong with your mA sensor transmitter if it is outputting mA. The datasheet is here, but my knowledge is too limited to make sense of it: That was a simple mistake on my part. PS – I will reply to the rest when I have rcv42 little more time later today. Jan 18, 3:
