  RE: EVM for either LMV1012 or LMV1032?

  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...

  RE: Dual Microphone noise cancelling application

  Hello Rudy Welcome to E2E, thanks for your interest in our products. As you have mentioned one solution is to design the circuit yourself, but I'd recommend you to have a look to the LMV1012 and LMV1032, you could use them in the first stage of...

  RE: equivalent of MAX9814 for electret mircophone signal amplification

  Hello Mahendra, You may take a look to the LMV1012 or LMV1032, these are specialized amplifiers for small form factor electret microphones. Best Regards, -Diego Meléndez López Audio Applications Engineer

  RE: 2-Wire Hydrophone Amplifier

  Joe, The LMV1012 is intended to be used with electret microphone capsules. Is this the type of transducer you are using? (Most of the hydrophones I have heard about have been low impedance moving-coil devices.) What is the signal bandwidth required...

  RE: Noise on TLV1012

  Hi, Nambirajan, Actually, I think your question is not super specific to the LMV1012. Basically, those caps provide traps for the frequency causing the interference. You should be able to calculate the cap value that will cause a trap for the offending...

  RE: Amplifying an Audio Signal

  Hi Ramin, Keep the supply to the microphone as clean as possible. The basic FET circuit does not have much PSRR. So pre-filter the supply line - especially if the power is derived from a switching supply. If you are curious, most likely the microphone...
