Application Notes

  • DC MOTOR SPEED CONTROLLER: Control a DC Motor without Tachometer Feedback
    PDF, 50 Kb, File published: Sep 27, 2000
    DC motor speed is often regulated with a closed-loop speed controller using tachometer feedback. It is possible, however, to control dc motor speed without tachometer feedback.
  • MTTF, Failrate, Reliability, and Life Testing
    PDF, 51 Kb, File published: Oct 4, 2000
    At Burr-Brown, we characterize and qualify the reliability of our devices through high temperature life testing. The results of this testing are quantified with such values as MTTF and failure rate. This information can be very valuable when used for comparative purposes or applied to reliablility calculations. However, this information loses its worth if it is not precisely understood and appropr
  • Power Amplifier Stress and Power Handling Limitations
    PDF, 55 Kb, File published: Sep 27, 2000
    To achieve reliable power amplifier designs you must consider the stress on the amplifier compared to its power handling limitations. Power handling limits are specified by the Safe Operating Area (SOA) curves of the power amp. Stress on the amplifier depends on amplifier load and signal conditions which can be evaluated with straightforward techniques.
