Figuring out how and why it doesn’t work. (Look, it’s smoking! Fix it!)

  • I looked at the specs for this mic at: http://www.analog.com/en/mems-sensors/microphones/admp401/products/product.html#similar_product_table….
    It indicated a possible issue. This mic system has a VERY low current out 250 uA, into a VERY low 200 ohm impedance. That is NOT much juice. Use an Op-amp step up, or a FET amplifier? It’s not working because there is nothing THERE!

No public wish lists :(
