| Using this general three-op-amp gain stage, you can implement the necessary gain and level shifting to signal-condition any sensor output for your application. RG adjusts the gain to either calibrate or quickly change the span. The voltages V+SHIFT or V-SHIFT, created by the corresponding resistor dividers of R+SHIFT1 and R+SHIFT2 or R-SHIFT1 and R-SHIFT2, respectively, position the offset at the desired level. |
