how do I set the gain of the amplifier
Finally, should I use the +5V rail for the other devices too
1.) EDIT: Am I supposed to supply pin 3 with 1/2 VDD (2.5V)?
2.) If I want the lowest reading from the photodetector to be 0V even though it receives light, how do I do this? Do I make the TLC272 output the differential voltage, and if so, how?
3.) Will I still need to use signal diodes in this design to limit the voltage?
