can u plz tell meee how to get a regulated 5v ouput if the input voltage is variable btween (2v and 10v )???
actually m using IC CA3140 for amolifying MILLIVOLTS TO VOLTS and then at the output pin of CA3140 i m getting dc variable voltage and i want it to be regulated to 5v so dat i can connect this supply to 8051 …
kindly helppppp Do you want the output of the OP-AMP to signal a ‘HIGH’ or ‘LOW’ to the microcontroller?
If yes, you can connect the output of the OP-AMP to the base of a transistor via a resistor and the collector of the transistor (also connected to 5V vcc) to your microcontroller. The transistor will then allow you to get 5V and GND on your microcontroller pin.
