Power Circuits for Instrumentation
Power Circuit Solutions for Instrumentation
High-performance instruments have some of the most stringent noise requirements to avoid interference with their sensitive front ends, which in turn places high demands on their power circuits. Budget constraints and the trend towards higher integration impose further restrictions on size, EMI, efficiency, and thermal management.
Value and Benefits
To meet today's demands, power products by Analog Devices offer innovative features including, slew-rate controlled switching power regulators, positive and negative rail generation, ultralow-noise LDOs with high-frequency ripple rejection, low-noise isolated power supply controllers, and system-in-package power modules.
Our broad array of products enables various power circuit topologies and system partitions to optimize for performance and cost at any power level.
