IN a paper read before the Institution of Electrical Engineers on March 6, D. C. Gall describes the design and behaviour of a direct-current amplifier, entirely alternating-current mains-operated, and ...

The electrification of vehicles has spurred an increased demand in accurate current measurement in new electronic drive systems, such as traction inverters, DC-DC controllers, battery managements ...

Over the years there have been many different audio amplifier designs which have found favour for a while and then been supplanted by newer ideas. One of them has crossed the bench of [Jazzy Jane], it ...

Using a resistor and voltage amplifier across it for current sensing presents a conundrum. On one hand, it appears to be near-trivial application of Ohm’s Law via I = V/R. It certainly looks easy: A ...

Texas Instruments (TI) rolled out its first current-sense amplifier to integrate a high-precision, low-drift shunt resistor, which can deliver highly accurate measurements over a wide temperature ...

The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has added “TC75S102F,” a new CMOS operational amplifier featuring industry-leading [1] ultra-low current ...

Vishay has introduced a precision isolation amplifier with 5kVrms isolation test voltage and 150kV/μs typical (100kV/μs min) common-mode transient immunity: VIA0050DD. “Isolation amplifiers in the VIA ...

Rohm has created a set of six current sense amplifiers with AEC-Q100 qualification for automotive use. They work with external shunt resistors, and there are two basic types: one (BD1423xFVJ-C) that ...

Here at Hackaday we’re no strangers to the colorful glow of LEDs. But what if there was more to appreciate beneath the surface? Back in 2011 [Windell] over at Evil Mad Scientist dug into a certain ...
