• RE: Intermodulation Distortion with AD1938

    Well I did some more testing, and discovered it isn't the AD1938, but the op-amps that are used to condition the signal (AD8608). I traced the tone and every time I made a jump over an op-amp circuit I saw a drop in the IMD.

    As far as I know, our…

  • RE: USBi Required for 64 bit ADAU1702 EVAL?

    Hi,

    Looking at the schematic for this board:

    http://www.analog.com/static/imported-files/user_guides/UG-072.pdf

    Please find Figure 7 on Page 12. The 49R9 resistors in the output circuit will create a divider with your headphones, what impedance are…

  • ADC Selection, Circuit Note CN-0254 opamp selection

    We are working on the design of data acquisition system.
    Specifications are:
    1. ADC Resolution: 16bit (minimum 14bit)

    2.Number of analog input channel 4 ch. (single ended 4ch., differential 2ch.)
    3.. Input Range -10V to +10V, 0 to +5V.
    4. Limit frequency…

  • Symmetry problem using AD8606ACBZ

    Trying to use the AD8606 in BGA package on a fully symmetrical layout, the two amps on the chip do not show identical behaviour. Configuration used is non-inverting amp w 2V ref and 200x amplification. A3B3C3 works as expected, whereas A1B1C1 always oscillates…

  • RE: ADA4530-1 Die level option

    Hi Mika,

    We currently don't have ADA4530-1 in a die level and I'm  not sure if we will have in the near near future. However, i found these few devices with 1pA typical bias current operational amplifiers in die/chipscale package. We have AD8691…

  • RE: ADMP441, SSM2529 Speech transmission

    Thank you for a thorough explanation.

    I have looked further at your catalog of op-amps. Since I am designing a portable unit, I examined the following, with 5 V supply:

    AD8605/AD8606/AD8608, AD8691/AD8692/AD8694, AD8655/AD8656, and the ADA4075-2.

  • RE: Driving analog data convertor AD7823 with an op-amp

    Hello Eyal,

    On the question of using a single-ended vs. a differential-output amplifier, it generally depends on the level of precision you are trying to obtain. Since the AD7823 is an 8-bit ADC, it's LSB size with a  1.2V reference, one-half of…

  • CN-0350 with multiple Inputs

    CN-0350 is designed for a single piezo sensor input. I need to change the design so it is able to sample from two piezo sensors in parallel.

    A simple solution would be to duplicate the analog part of the circuit and use a 2-channel ADC (e.g. AD7091R-2…
