ADS1602: ADS1602 SNR test software

James Chiu

Part Number: ADS1602

According to the following link, I know there's NO ADS1602 EVM.

ADS1601: Is there EVM or reference design of ADS1601 chip? - Data converters forum - Data converters - TI E2E support forums

According to the following link(slau147), I know there should have been a ADS1602 EVM long time ago.

I'd like to know how you test ADS1602's SNR? There might be a software that can read from EVM and show SNR result(like below).

Can you give the software download link? Let me test my ADS1602's SNR on my PCB.

    Hi James,

    TI's Analog Engineer Calculator can be used to calculate and show the FFT result including SNR, it cab be downloaded here. Below is a screenshot, fyi.

    To do that, you will have to do

    • Apply a clean full-scale input sinewave to you ADC on your circuit board, then capture the raw data.
    • Load your raw data into the Data Analysis Tool Kit page according to the specified data file format which can be checked by clicking the 'Help'.

    Best regards,

    Dale
