Redefining low power in current-sense amps

摘要

Sensing and controlling supply current flow are a fundamental requirement in most all electronic systems from battery-operated, portable equipment to mobile or fixed-platform power management and dc motor control. High-side current-sense small form factor, low supply-current operation, wide operating supply-voltage range, low input offset voltage (V_(OS)) and gain errors, and fixed-gain options, design engineers now have even more options for high-side current-sensing amplification. As a result, new CSA enhancements enable the next generation of battery-powered, handheld portable instruments addressing power management, motor control, and fixed-platform applications.
