Convert 0 to 10 volt into from 5 to 0 volt

Dear all my friends
i have an input volt from 0 to 10 volt ... i need to change it to 0 to 5 V with reverse action ... means i need when input is 10 the out is 0 and when input is 0 the out is 5 v

how can i get this

Thanks in advance

Re: Convert 0 to 10 volt into from 5 to 0 volt

your requirement does not specify whether you want linear response (i/p 0 to 10v and o/p 5 to 0v with inbetween ranges)
or for only extremes.( with 10v i/p 0v o/p and 0v i/p 5v o/p.)
 

Re: Convert 0 to 10 volt into from 5 to 0 volt

I read it as inverting amplifier specification, G = -0.5, +10V output offset.

Simple inverting OP circuit, R1 = 2*R2, n.i. input biased with 3.3V reference voltage.

I need a linear response ... for Fvm please give schematic ... thanks very much

Hi,

for Fvm please give schematic

Is it asking too much to google for "inverting amplifier circuit" on your own?

You will find many thousands of hits. Almost all describe the same.
Many of them have detailed description about operation and part value calculation.

Here you have it with the explanation: https://payhip.com/b/5Srt

Below is the LTspice simulation of the inverter circuit with the required offset to give 5V to 0V from a 0V to 10V input with a single 5V supply voltage.
For other supply voltages, the ratio of R2 and R4 will need to be changed.
If high accuracy is needed then the voltage to R2 should be from a voltage reference.

I apologize for my post above. I forgot to check the preview of the e-book. The inverting configuration is not in the preview, but in the paid version. Here you have free materials about the inverting configuration that should help you to understand this configuration:

Hope that will help.
