A version of thie article appeared in the February 2012 issue of Test & Measurement World. See the PDF. Many industrial systems use the 4–20-mA loop to transmit measurements from sensors to displays, ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

The 0- to 20-mA current loop isa reliable means of data communicationin industrial applications.These circuits use a precision shunt inthe receiver to convert the current signalinto a voltage signal.

The new laser diode driver iC-HTP permits microcontroller-based driving of laser diodes with common cathodes or P-type laser diodes in CW mode (Continuous Wave). With this device either Automatic ...

Nanopower Semiconductor, a European fabless semiconductor manufacturer, announces that their award winning nPZero power-saving integrated circuit (PSIC) is now in volume production enabling, original ...

Microchip is aiming at motor control by combining a triple half-bridge mosfet gate driver, a 100MHz processor and CAN FD transceivers in the same IC. Other members of the family offer LIN transceivers ...

The new laser diode driver iC-HT permits microcontroller-based activation of laser diodes in CW mode. With this device laser diodes can be driven by either the optical output power (using APC), the ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

Drawing and analysing flowchart diagrams involves elements like count, compare, macro, do macro, end, increments, decrements, and expressions. Microcontrollers (PICs) are used in control systems, ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.
