+/-10V (Dual 10V) to Single-Supply Signal Converter for ADC

This board will make your work easy if you want to interface +/- 10V (Dual 10V) device or sensor to single-supply signal ADC. This tiny project has been made for industrial and process control applications and provides an easy interface between +/-10V (Dual 10V) sensor or device to single-supply ADC. Connect +/-10V sensor/device to pin 3 of connector CN1, and circuit outputs 0.5V to 4.5V at pin 3 of connector CN2. The operating supply of the circuit is 5V and it draws few milliamps of current. The project is also provided with optional precision Ref voltage for accurate output.
