• RE: Aliasing in sigma-delta ADC output?

    Hi,

    doesn't any one have a clue of that common principle?

    It seems that I have touched a sore point.

    Because even if there is no signal frequency in that range, there is definitely noise in this whole band,

    some which get aliased to near DC …

  • RE: AD7764 grounding in EVAL board

    Hi Abhijit,

    A single full ground plane is employed for the AD7764/5 evaluation board. Early in the development we decided to use a single ground plane - due mostly to experience on other boards where we had seen better performance when the largest whole…

  • Photodiode amplifiers for 24 bit ADCs

    I would like to interface a photodiode transimpedance amplifier to a 24bit ADC (AD7765, AD776, AD7767 or similar). The largest source of error appears to be the drift of the transimpedance amp (TIA), rather than noise.

    We prefer to use a linear amplifier…

  • Piezoelectric sensor signal conditioning

    Hello,

    I need a piezoelectric signal conditioning circuit with the highest possible dynamic range to feed an AD7765. The piezo sensor has a high leakage resistance of 20 GOhm. The signal has first to be impedance converted by a charge amplifier or an…
