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, ...

With just a few components, you can provide a translated signal from industrial and PLD sensors that connects safely to a microcontroller, with the added bonus of supplying 7.5 mA of regulated power.

The MCP120 is a microcontroller voltage supervisory circuit with open drain output. This voltage supervisory device is designed to hold a microcontroller in reset until the supply voltage has reached ...

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, ...

Voltage-to-current converters that feed grounded loads are common in industrial measurement and control applications. The conventional "textbook" circuit uses both positive and negative supply rails.

[Hugatry] wanted to replace the adjustment pot on an LM2596 buck converter with a microprocessor-controlled voltage. The regulator IC uses a divider to generate a 1.25V reference from the output. The ...

A microprocessor is an integrated circuit that contains no memory. A microcontroller has the ability to store information. The size of a circuit can be significantly reduced. This is because ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...
