    Hi guys, I just bought an OPT101 (Monolithic Photodiode and Single-Supply Transimpedance Amplifier) and I would like to test it. Kindly give me some ways on how to test it properly. Thanks!

    What do you want to test: basic functionality, compliance with full specification, or...

    To test the basic functionality, connect pins 3 and 8 to common, and pin 1 to V+ supply (3V-30V),
    Connect pin 4 to pin 5.
    Apply power to the circuit.
    The voltage at pins 4,5 should now vary with a change in light on the IC.
    The device is very sensitive so it takes only a very low light level to give a maximum voltage output.
