    Help with identifying component

    The marking says "AXC8" and it has 5 pins. It looks like a SC70 package.

    I tried to take a photo through a microscope lens, so I apologize for the poor quality!

    Re: Help with identifying component

    Maybe this: Torex XC6211B132MR

    I can't find the data sheet for above part number.

    The package that i have is SC70/SOT323 with 5 pins.

    Based on the circuit, it looks like an op amp/comparator.

    Thanks!

    Re: Help with identifying component

    That torex part is a voltage regulator. Would that make sense?

    There are two of them in the circuit, I don't think so. The dimension of the package is 2x1.25 mm so I think that corresponds to SC70 or SOT323.

    This is from an open oven quartz crystal oscillator, trying to figure out where a fault is coming from.

    I've seen Microchip marks their part numbering information using the first 2 characters for client info, and the last 2 for part numbering traceability.

    Re: Help with identifying component

    I see that the Torex part uses a similar marking scheme, the package is however larger SOT-25 (SOT-23-5). Means the guess seems wrong at second sight.

    5-pin OPs have one or two standard pinnings, you won't necessarily need to know the exact type once you have verified it's an OP.

    Re: Help with identifying component

    It looks like it's a temperature sensor of some sort actually.

    The pinout is as follows:

    NC
    GND
    OUT
    supply
    GND
