• OP213 Noise Spectral Density vs Noise Peak to Peak

    Hello,

    I am planning on using a OP213 for a low noise circuit. I see the datasheet and it is stated that the peak to peak noise over 0.1-10 Hz bandwidth is 120 nV peak to peak. I do the hand calculation and I get a noise of about 3 to 4 times that value…

  • RE: voltage to current converter

    Hi AGA,

    I found an RC combination (R3, C1) across your 2.2H inductor which gives a stable response, as shown below:

    AC simulation looking for Loop Gain confirms adequate Phase Margin with this modification:

    I don't think output current capability of…

  • RE: About noise mesurement

    Hi Tarzan,

    Good Day.

    The Active BPF that was used in this article will be likely made up of: Gain Stage – HPF – LPF. The first stage is a gain stage where it will amplify the noise from the output of OP213 which has a gain of 1000. Next stage will be…

  • AD7707:input impedance and currents

    I´ve got some questions about the specifications of the AD7707. I´m working
    actually with the low level inputs. I didn´t found clearly values about the
    input impedance or input currents in buffered or unbuffered mode in the data

  • Noise optimizing AD8599 &&

    Good day,

    I have a task to optimize noise in BW 10Hz - 10kHz.

    Voltage gain shall be around 20..50. OA connected directly to source of signal,

    which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,

    where R1 connected…

  • operational amplifier without internal bias-compensation

    Do you have amplifier (opamps) without internal bias-compensation?

     

    We have two different types of bipolar amplifiers in our portfolio. Simple
    bipolar and bias-compensated bipolar amplifiers.
