ADS8317: Differential amplifier for ADS8317

Part Number: ADS8317
Other Parts Discussed in Thread: THS4551, THS4521


I would like to use THS 4131 for the input amplifier of the ADS8317.

Is there a reference design for the differential input of the ADS8317?

Is there any op amp recommended other than THS 4131?

Best regards,


  • Hi Seishin,
    If your design does not require the bipolar +/-15V supply, the THS4551 and THS4521 are optimal uni-polar supply (5V) fully differential amplifiers that can drive the ADS8317.  Attached is a circuit example using the THS4551 with Gain=1V/V.  Depending on your input signal requirements: signal amplitude,  common-mode voltage and frequency; we could modify the circuit for optimal gain and bandwidth. 

    Please let us know if you have any questions.

    Thank you and Best Regards,

  • Dear Luis,

    Thank you very much for your detailed information.
    The power supply of the operational amplifier uses uni-polar.
    I will make it referring to this circuit example.
