10.2.1 Design Requirements

The requirements for this application are:

  • Single-ended to differential conversion
  • Attenuation by 0.5-V/V gain
  • Active filter set to a Butterworth, 170-kHz response shape
  • Output RC elements set by SAR input requirements (not part of the filter design)
  • Filter element resistors and capacitors are set to limit added noise over the THS4561 and noise peaking
