As EDN’s Design Ideas editor, I see a range of design submissions, from good, to not so good. A recent DI I turned down for several reasons included a high-side current sense circuit with implementation problems. This got me thinking about the different ways to accomplish current sensing on a voltage rail. At their heart, […]

Texas Instruments says it is making, “high-accuracy measurement more attainable with the first current-sense amplifier to integrate a high-precision, low-drift 2 mΩ shunt resistor,” – the device can cut calibration effort, system cost, and footprint for test and measurement, communications load monitoring, and power supplies. For highly accurate measurements over a wide temperature range, TI’s
