  • IC Temperature Sensor Accuracy Compensation with a PICmicro Microcontroller
    Microchip Technology Inc. provides a number of analog and serial-output Integrated Circuit (IC) temperature sensors. The typical accuracy of these sensors at room temperature is within one degree Celsius. However, at hot or cold temperature extremes, the accuracy decreases non-linearly. Typically
  • Hot tips on IC temp sensors
    , the temperature-sensing material should keep the same temperature coefficient over its complete measurement range creating a linear response. Unfortunately, the temperature coefficient of most materials changes for different temperatures producing a nonlinear measurement. Many materials have
  • High-Speed Lithium Ion Battery Charger
    Driven by the need for untethered mobility and ease of use, many systems rely on rechargeable batteries as their primary power source. The battery charger is typically implemented using a fixed-function IC to control the charging current/voltage profile. The C8051F300 family provides a flexible
  • | Electronics Industry News for EEs & Engineering Managers
    cash for equity deal Samsung on SLC vs MLC flash memory How prices plunged after September calm ASML on immersion and Q3 results What analysts are saying about Lam Research Anadigics acquires assets of Celeritek subsidiary Strong growth predicted for the linear market Cypress beats 3Q forecast
  • Protection For Switching Regulators
    Step down regulators are used to convert a higher DC voltage to a lower required DC voltage. Switching regulators offer higher efficiency than the linear regulators, excellent load step response and higher output currents. They are also more expensive than linear regulators and produce more noise
  • Improving Motion Positioning With Dual-Loop Control and Scurve
    utilizing a Magellan (R) motion control IC. This card connects to two motors and four encoders: one rotary encoder on each motor, and one linear encoder on each axis. To maximize positioning accuracy, a dual encoder configuration (dualloop control) is used. This powerful technique allows one
  • Temperature Measurement Circuits for Embedded Applications
    will be compared with a frequency output RTD oscillator circuit, along with design examples using serial and analog output silicon Integrated Circuit (IC) sensors. In addition, a Programmable Gain Amplifier (PGA) circuit will be shown that can increase the effectiveness of the Analog-to-Digital Converter (ADC) bit
  • Measure Angles on Rotating Systems with High Resolution
    applications integrated encoder ICs, such as the iC-MA, are suitable as it includes all functions to sense and process the rotating magnetic field of the permanent magnet placed on top of the IC. Innovation is provided by a single device, such as the iC-ML which integrates linear Hall sensors and encoder
