  • Bridge Sensing with the MCP6S2X PGAs
    . current requirements to drive the resistor array in the. and gain adjustability, allowing an easy interface to a. MCP6S26 during ac operation. variety of sensors and/or channels in the same applica-. tion circuit. With an INA, the gain and reference voltage. At the output of the PGA, an anti-aliasing
  • AN117 Basic Bridge Circuits
    Bridge circuits have been in use for well over 150 years. To date, the bridge is still the most economical circuit technique for accurately measuring resistance. The original bridge circuit topology has had many unique modifications and has been applied to applications such as AC measurements
  • LVDT, Half Bridge and Digital Transducer Theory
    and IP68 Sensors (SR). AC Miniature LVDT (MD, SM, OP). Miniature LVDT Micro Series (MD). Miniature LVDT SM Series (SM). Miniature LVDT Optimum Series (OP). DC Miniature LVDT (DFg Series). Analogue Gauging. Analogue Gauging Probes (Spring Push). Analogue Automatic Probes (Pneumatic). Analogue Specialist
  • Power Measurement Application Note
    Power is the rate at which work is done (work/time). It is also the rate at which energy is. generated or used. For dc systems, power is expressed in watts: P=VdcAdc. For ac systems,. the determination of power is more complex. The voltage and current in an AC circuit. periodically change direction
  • Brushless DC Motor Control Using PIC18FXX31 MCUs
    A PICDEM TM MC demo board was used to develop, test and debug the motor control code. The PICDEM MC has a single-phase diode bridge rectifier, converting AC input to DC and a power capacitor bank that keeps a stable DC bus. A 3-phase IGBT-based inverter bridge is used to control the output voltage
  • Basic Output Generator Excitation and Demodulation Requirements for USD Gyroscopes
    , are not as stringent as. those for gyroscope spinmotor excitation. A simple oscillator, appropriate for gyro pickoff functional. testing based on a modified Wien bridge oscillator and an LC resonator operated by a bi-polar (±DC). power supply is shown below in figure 1. Figure 1 – Simple AC Sinewave
  • The Problem With Current Limit
    further advantage of the PAD121 compared to the old current limit. circuitry is that the PAD121 better utilizes the available current capability of. the power op amp. In the old circuit once the current limit trip point is set it. acts on DC and AC signals equally. With the externally set time constant
  • Medical Device Link .
    (MEMS) with machines fabricated at the millimeter or molecular level have already become a reality. For example, the idea of an electronic device stimulating the heart to beat was considered lunacy in 1930, when the first external pacemakers required ac power and penetration of the chest cavity
