It is comprised of a high resolution Mixed-signal Front-End and of a dense Power and energy Computation Engine to achieve at the system-level a class accuracy as high as 0.1% (class accuracy of the product is 0.05%) over a range up to 1/10,000.
Key Benefits
- Embedded Computation Engine for utility biling applications
- Low noise Programmable Gain Amplifier (PGA), to reach the best class accuracy with each type of sensors
- Embedded power management for the best resilience to power supply noise
