With the proliferation of battery-operated Internet-of-Things (IoT) devices capable of long service intervals, designers need precise measurement of a device's current draw and power consumption. The Joulescope JS220 meets this requirement and many other higher-current measurements as well.
Brian has lots of experience designing lab instruments from his university days. But that was before modern MCUs were available that have rich sets of analog functions on-chip. Here, Brian steps through how to design lab instruments using the Cypress PSoC 5LP MCU.
