XTR200: PWM Input

Viktor Schneigelberger

Part Number: XTR200


Hello,

Are there any app notes or design guides available for XTR200 using an PWM input?

Anything to consider? Filter required? ...

 

Regards,

Viktor

    Hi Viktor, 

    What resolution is the customer looking to achieve with the PWM input? The general circuit tends to look like PWM signal out -> Low pass filter -> input to XTR200. The design of the filtering depends on the ripple tolerance and PWM frequency. 

    This TI design shows the PWM filter with a test circuit but explains the design process as well: tidu027.pdf

    Please let me know if you have further questions.
    Thank you!

    Regards,
    Ashley
