I need a system which Detect the light (with photo Diode),which is above specified limit, and give output as digital High or Low (Eg: If the intensity of light above the threshold value the output will be high and low below some specified threshold it should be low)
Now this can accomplished by combination of discrete component like charge amp, differential amp, and a Schmitt trigger. Can anyone suggest suitable IC with all this functionalities to gather as a single IC. Thank you
