Current-sense amp integrates precision shunt resistor, in single package

Leave a Comment / Tech News Updates / By

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 …

Precision programmable current source uses two ICs

Leave a Comment / Tech News Updates / By

This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 illustrates the basic topology, taking advantage of tightly matched on-chip resistor ratios instead of relying on absolute tolerances. The IIN current source gives rise to a …
