A current-sensor would be useful in a lab power supply. This app note is about chaining two current-sense chips to use at high voltages: Using a transistor as shown, you can double the allowed voltage limit on a current-sense amplifier by stacking two such amplifiers one upon the other. The voltage signal from the bottom […]

App note: Simple constant-power driver
This app note describes a simple, inexpensive constant power driver: A combination current-sense amplifier and multiplier (MAX4211F) senses both the current through and voltage across the load, and supplies at one of its outputs (POUT) a voltage proportional to the continuous product of those variables, i.e., proportional to the load’s instantaneous power. External op amps […]
