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 …
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…
I have gone through the website of analog devices, but was not able to find the IBIS model of AD7764 ADC. I was trying to perform the SI analysis at the digital section of the ADC with only the input load capacitance of the pin given in the datasheet…
I wanted to know what is the maximum and minimum ripple required for the voltage pins AVDD1 and DVDD. We are trying to give 2.5V from the switch mode power supply but the AVDD1 pin is connected to the modulator.
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…
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…
