Analog engineer's calculator




The Analog Engineer’s Calculator is designed to speed up many of the repetitive calculations that analog circuit design engineers use on a regular basis. This PC-based tool provides a graphical interface with a list of various common calculations ranging from setting op-amp gain with feedback resistors to selecting appropriate circuit design elements for stabilizing an analog-to-digital converter (ADC) drive buffer circuit. In addition to being useful as a stand-alone tool, this calculator pairs well with the concepts described in the Analog Engineer's Pocket Reference.

  • Expedites circuit design with analog-to-digital converters (ADCs) and digital-to-analog converters (DACs)
    • Noise calculations
    • Common unit translation
  • Solves common amplifier circuit design problems
    • Gain selections using standard resistors
    • Filter configurations
    • Total noise for common amplifier configurations
  • Performs PCB parasitic calculations (e.g., R, L, and C)
  • Finds sensor output values for common sensors (e.g., RTD, thermocouple)
  • Solves common passive circuit problems (e.g., voltage divider using passive components)

  • Downloadable installer with a Windows®-compatible .exe file
