  • Understanding Current Sinking, Current Sourcing, and Ground Loops
    You've just purchased some current to pneumatic transducers and are ready to try them. Each transducer has been carefully installed according to the manufacturer's recommendations and wired to its own 4-20 mA analog output. All of the transducers are being powered by a common 24 VDC power supply
  • Current to Voltage Conversion for BAS Systems
    One of the differences that exists among the various BAS systems that are available today is the type of signals that are acceptable as analog inputs. For example, when it comes to DC voltage and current inputs, some systems can only read a voltage while other systems can be configured to handle
  • Analog to Digital Conversion
    times of 250 ms or longer. The method is usable for both voltage and current conversion and uses a software calibration technique that compensates for time and temperature drift as well as component errors. PIC16C5X microcon-trollers are ideal for simple analog applications because: ? Very low cost
  • Digital does analog
    band's latest hit single. To reproduce sound, a speaker moves a cone or diaphragm in response to a change in current or voltage. Because sound is analog, the current or voltage tracks over a broad range of values to reproduce the exact motion to create the proper pressure wave. Instead of the full-on
  • MCP2030 Three-Channel Analog Front-End Device Overview
    . The RSSI current output is LFDATA/ linearly proportional to the input signal strength. Device LCZ 96 CCLK/SDIO features are controlled by the programming of its internal V V 87DD DD Configuration registers. The device has programmable internal tuning capacitors for each input channel. The user can program
  • Battery Fuel Measurement Using Delta-Sigma ADC Devices
    of time. ticated fuel gauging function for accurate applications. The battery voltage and current measurement is This application note reviews the battery fuel measure- achieved using an analog-to-digital converter (ADC). ment using the MCU and ADC devices. The accuracy of the fuel management relies
  • Medical Device Link .
    reviews current medical applications of spintronic sensors, their construction and operation, design considerations, and possible future developments related to medical devices. Military applications provided much of the impetus for developing spintronic sensors. In the medical industry, these sensors
  • Medical Device Link .
    , physiological processes emit very weak signal levels, which makes the signals vulnerable to RFI. Second, the input signals are impossible to shield adequately because the end of the cable connected to the patient cannot be terminated. Third, leakage current limitations restrict capacitive filtering
  • Medical Device Link .
    Performance in Small Packages Until recently, medical equipment in hospitals and practitioners' offices was generally considered more accurate and more precise than portable counterparts used at home. The current trend, however, is changing rapidly to accommodate not only average consumers, but also
