Hi All,
I am using a sensor which gives 0-1V DC voltage for its full range. I want use the internal 10-bit ADC of the controller. But for the input voltage range for the ADC is 0 to 3V. So I want to convert this sensor output of 0-1V to 0-3V by using an amplifier circuit.
I tried with the OPAMP circuit, but it didnt work without the negetive supply voltage. Is it possible to use the op-amp itself without the -ve supply? Or should I go for a simple transistor amplifier?
Please suggest. Also suggest a simple working circuit for both Opamp and the transistor.
