  • RE: ADA2200 input clock question

    Hi Jack,

    The ADA2200-EVALZ requires programming the on-board flash to change the ADA2200 configuration.  You program the flash with the desired register configuration, then boot the ADA2200 from flash and the part is programmed.


  • RE: ADA2200 synchronisation with sigma-delta ADC (AD7768)

    Hi Michael,

    To keep the AD7768 and the ADA2200 synchronized, you need to keep 2 things in sync.  The first is the MCLK signal of the AD7768 and the CLKIN signal of the ADA2200 need to be derived from the same clock, so there is no phase drift between these…

  • Required explanation of "QUICK START AND SETUP PROCEDURE" procedure for ADA2200-EVALZ User Guide

    Dear All,

    I am using ADA2200-EVALZ from analog devices for my lock-in amplifier project. 

    "QUICK START AND SETUP PROCEDURE" procedure for ADA2200-EVALZ  mentioned in User Guide is not self explanatory. Expected output voltage is not mentioned in…

  • Comment on ADA2200: Replacing RCLK signal with DAC output

    So it seems to work with or without setting the bit  "Clock source select" in the register "Analog pin configuration"  : fair enough.

    My goal is to build a real lock-in, so able to give amplitude and phase. I put a second ADA2200…

    Dear brianharrington,

    I have a question about the ADA2200 ask you.

    Single-chip ADA2200 lock amplification, followed by AD7192, in order to reject output spurs
    that are created at evenmultiples of PSD, set the AD7192 output data rate is equal to the…

  • ADA2200 spice model

    Hello All,

    For the ADA2200 a model is supplied which should work on the ADIsimPE simulation tool.

    However, the ADA2200 requires some register settings but the digital interface is not part of the model.

    So, how do I influence or simulate the ADA2200…

  • RE: How to use ADA2200 Synchronous Demodulation for my application

    One way to generate a sinewave excitation signal for the load that is synchronized to the ADA2200 RCLK signal using a DDS chip like the AD9838,  is as follows:

    Drive the AD9838 MCLK input and the ADA2200 CLKIN input from a common clock source, then program…

    Original Question: ADA2200 Encrypted Model by Wade.Calcutt

    Is it possible to get an encrypted model for the ADA2200 added to the ADIsimPE library or posted here? I would like to simulate it with an simple analog front end but after adding the components…

  • RE: ADA2200 EVALZ Help

    Hi Dakotah.  

    Your understanding is correct.  The excitation voltage frequency of the bridge needs to be synchronous to the sampling frequency of the ADA2200.  You always want to sample the bridge at the same point in the excitation period.  Have you looked…
