The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

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 ...

I had lunch the other day with Bob Pease and Marcello Salvatierra, an apps engineer with National Semi’s amplifier group. Marcello had observed a rather serious problem with the classical high-side ...

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 ...

Texas instruments has introduced a precision bi-directional current sense amplifier than can measure voltage drops across shunt resistors over a common-mode range of -5 to 110V, with survival across ...

Santa Clara, CA and Kyoto, Japan, March 09, 2023 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced the BD1421x-LA series of space-saving, high accuracy current sense amplifier ICs for industrial ...

In recent years, the automotive market has seen a growing adoption of 48V systems alongside conventional 5V/12V power supplies, fueled by the rising popularity of electric vehicles. Furthermore, as ...
