  • RE: EVM for either LMV1012 or LMV1032?

    LeonardEllis
    LeonardEllis
    Hi Paul, Since the idea behind the LMV1012 is to replace the JFET already inside the ECM (Electret Condenser Microphone), and the challenges of keeping the device as close to the microphone as possible, it is assumed that the ECM itself will be used…

    Hello citizen, A search of TI.com did not yield any similar TI products to the FAN3852. There is the LMV1012 microphone preamp, but its doesn't have a built-n A/D function. Regards, Thomas Precision Amplifiers Applications Engineering

    Jota, You're right the preamp should be powered, this is why phantom power is required. You can see this preamp as a LMV1012, the pull up resistor at the output is the phantom power. You can then connect this output (through the coupling capacitor) to…
