  • Application Note - Isolation of Follower Signals
    Dart drives with speed-pot inputs can also follow a voltage control signal instead of the speedpot. by connecting the voltage signal leads to the WIPER and POT LO terminals the POT HI. terminal open. If a voltage signal is used in place of the speed-pot, the signal must be isolated from ground
  • Power Design Considerations For LED Applications
    DACOUT, load the serial input register of the DAC with the code in Figure 1. In order to have 4mA through the current loop for 0V DACOUT, we use an offset voltage reference of 2.5V. In Figure 2, A1 is connected as a voltage follower amplifier which drives a very high impedance MOSFET Q2 and its
  • Programmable Current Loop

  • Agilent: Five Hints for Debugging Microcontroller-Based Designs
    Hint 1: Verifying quadrature encoder signals in a motion control system Using a mixed analog and digital signal oscilloscope to simultaneously monitor the signal levels of a quadrature encoder, an LS7083 converter chip, and a motor's positive lead. Hint 2: Implementing a simple voltage follower
  • AN08: Polynomial Gain Correction for RadEye Sensors
    the accumulated charge from the pixel to a readout amplifier before any charge-to-voltage conversion takes place. The active pixel sensor, on the other hand, measures a change in voltage corresponding to the signal charge directly at the pixel by employing a source-follower FET. This approach has many advantages
