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
- Optimizes Power Design: Supports varied topologies and system partitions across power levels.
- Reduces Noise Impact: Ultralow-noise LDOs and isolated controllers improve ripple rejection.
- Simplifies Integration: Slew-rate controlled regulators and SiP modules save space and design time.
- Speeds Development: Robust tools and support accelerate time to market.
