• RE: SSM2019 single supply with balanced input

    Hello Carlos,

    I don't know if this is valid for you, but since your reference is bias with V+/2, you should raise both of your inputs (+)IN (-)IN with a 10k resistor to V+/2. This should make it. This amplifier is fantastic! I've used with similar…

  • SSM2019 with digital potentiometer?

    Hello all,

    I'm a current University student taking on a project that involves a digitally controlled microphone pre-amp.

    I am a bit new to this so apologies if the question is a bit basic!

    I have some experience using inverted op amp setups using raw…

  • SSM2019使用问题

    SSM2019供电,使用两节相同电池,只是一节11V一节9V,电池串联,+11v接引脚7,-9V接引脚4,0V接引脚5,连接后9v的电池变为固定0.75v,输出也不能正常放大,请问是什么原因呢?

  • RE: alternative audio mixer IC for SSM2163

    Hello,

    Unfortunately we don't have a direct replacement for SSM2163,  But in case your interested on other option that uses a discrete solution, you can look at the SSM2019. The part is a self contained pre amplifier with noise level at 950pVrtHz and…

  • RE: 5532 1st order bandpass for electret mic preamp

    Are you using the SSM2019 microphone preamp (not SSM2219)? That is an audio preamp with the one external resistor gain adjustment, as you've mentioned. On page 6 of the SSM2019 data sheet, there is a table showing the different resistor values and gain…

  • RE: Audio Codec (ADAU1961) Specification detail

    Hello Boosun,

    It is unusual to find an actual dynamic microphone on a headset. They are usually electret condensers that require power and have a built in amplifier. So the PGA gain in the 1961 is plenty for those microphones. For a dynamic mic with…

  • RE: Connect microphones to ADAU1979

    what do you mean by 'standard' microphone ?

    if it means dynamic mic, you don't need power to mic

    if anything else, power supply circuit should be designed outside ADC

    with anything, the preamp is needed that amplify audio signal from mic…
