An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...

This application note discusses the REF pin functionality in the indirect current-feedback architecture for instrumentation amplifiers. This article compares the importance of a REF buffer in a ...

The device supports common-mode voltages ranging from -4V to 100V and is AEC-Q100 qualified, making it suitable for use with industrial DC buses and automotive boardnet standards, including 12V, 24V, ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

Editor’s note: I am pleased to have Gustavo Castro as this month’s RAQ author. Castro is a system applications engineer in the Linear and Precision Technology Group in Wilmington, MA. His main ...

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

The low operating current of STMicroelectronics’ TSU111 nano-power op amp is on par with the leakage current of some low-cost capacitors, and would take over 25 years to discharge a 220mAh CR2032 cell ...

Q. Why buy an expensive comparator when an op amp is just as good? A. Because it isn't. My advice to anyone tempted to use an operational amplifier (op amp) as a comparator is the same as Mr. Punch's ...
