Hello,
I want to connect the nanovolt amplifier A22 to the ADS1282. (http://www.emelectronics.co.uk/spec/A22.html)
The amplifier is dimensioned by Rfb, so that the maximum output voltage is + /-2.5V.
I want to know if the schematic below is well dimensioned or not! That is, AVDD=2.5V, AVSS=-2.5V, AINP1=AmpOutput, AINN1=GND, VREFP=2.5V and VREFP=GND, is OK or not?
There is another possible schematic better than this?
Best regards
Ivo Bernardo
