  • Forum Post: Pre-amp for interface of a Balanced/MC mic into 2-wire electret mic input

    Tim Craig Tim Craig
    I must put together a single channel low-voltage (~2v) balanced mic compatible preamplifier in order to interface a dynamic/balanced/moving coil mic to a host circuit that has been designed to connect to 2-wire 'phantom' powered electret capsule (ECM) My circuit must operate on the small power...

  • Forum Post: RE: LME49724 Input Resistance

    Eric Koester Eric Koester
    Same topic - input inpedance of the LME49724. So, if I wanted to design for a 600 Ohm input impedance I would have the series input resistors R1 and R2 (from page 22 Figure.16) as 300 Ohm resistors? And then the feedback resistors R3 and R4 would just be sized in order to give me the amount of gain...

  • Forum Post: LME49724 is a balanced audio op amp, correct?

    Eric Koester Eric Koester
    Hi, I want to know if the LME49724 is a balanced op amp similar to the Burr Brown INA163 and the THAT1570 ? With the INA163 and THAT1570, the input impedance is said to be set with resistors that are parallel to the + and - inputs of the op amp, rather than with a series resistors connected to the +...

    KIRAN KUMAR4 KIRAN KUMAR4
    Thanks Christoph Neuhaus . But could you tell me why the non-inverting terminal is to be provided with a voltage Vcc/2 ?? Does the combination R4,C3 &R5 works as an integrator ? If yes how would the output waveform be?

    KIRAN KUMAR4 KIRAN KUMAR4
    can anyone tell me how deos the circuit attached below works?? i need to know which kind of filters are being used in the circuit? What is the use of an RC component at the non inverting terminal of opamp ? Does that RC in the feedback loop make an integrator or differentiator. ? kindly reply at the...
