  • Temperature Strip-Chart Recorder Uses Parallel Port

    By Ed Rojas, March 01, 2004

    A simple, inexpensive method for building a temperature strip-chart recorder involves a parallel port that communicates with four TMP121 IC temperature sensors (Fig. 1). The sensors communicate via the...

  • Design Briefs: Equations for determining common-mode performance

    By Art Kay, August 04, 2003

    Using Equation 2 (below) with Excel can be a useful tool in determining a range of possible CMRR values given a resistor tolerance. First, generate a set of random numbers with a normal distribution based on the tolerance you intend to use in...

  • Increase Common-Mode Range For Fully Differential Amplifiers

    By Art Kay, August 04, 2003

    Fully differential amplifiers have grown in popularity because of their low distortion, excellent noise rejection, and the simplicity of interfacing them with differential analog-to-digital converters (ADCs). This application shows how to increase the...
