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, ...

GUEST OPINION: Choosing a suitable microcontroller is a crucial stage of any electronic system creation. MCU works as the brain of an application, managing the communication between components and ...

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.

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 future’s cheap and yellow.

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 ...

[Lujji] is playing around with the STM8 microcontroller. In reviewing the official documentation for this chip, he read the external clock can be a sine wave, a triangle wave, or a square wave with a ...

IC timers are programmable semiconductor circuits that generate or set timing for electronic circuits. These chips function as single or multi-function units. An IC timer works by charging and ...

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 ...
