The LT2940IMS#PBF is a specialized integrated circuit from Analog Devices designed for power and current monitoring applications. It accurately measures high-side current and differential voltage, multiplying them to produce an output current proportional to instantaneous power. This device handles bidirectional currents and bipolar voltage differences, enabling indication of forward and reverse power flow.
Key features include four-quadrant power measurement with ±5% accuracy and ±3% current measurement accuracy. It operates with a supply range of 6V to 80V and supports a high-side sense voltage from 4V to 80V, with a maximum of 100V. The output bandwidth exceeds 500kHz, and it includes an integrated comparator with open-collector outputs for power level monitoring. The LT2940IMS#PBF is available in a 12-lead MSOP package, suitable for surface mounting.
This IC is ideal for board-level power and current monitoring, line card and server power monitoring, power sense circuit breakers, and power control loops. Its current mode outputs simplify scaling, filtering, and time integration with external components.
