A smarter
approach to metering.
Cirrus Logic Analog Front Ends (AFEs) are the first
choice for today’s smart metering solutions.
Unlike expensive SOCs, our AFEs allow the
flexibility of designing with a wide range of third
party microcontrollers to optimize for your specific
application requirements.
Don’t spend time worrying about how to make an
SOC fit into your design. Make the smarter choice for
your metering needs with Cirrus Logic’s flexible, cost-
effective AFE solutions.
