IR Receiver
The LMV7219 is an ideal candidate to be used as an infrared receiver. The infrared photo diode creates a
current relative to the amount of infrared light present. The current creates a voltage across RD. When this
voltage level cross the voltage applied by the voltage divider to the inverting input, the output transitions.
