Cirrus Logic CS5480/CS5484/CS5490

Cirrus Logic CS5480/CS5484/CS5490

The functionality and performance of the CS5484, CS5480 and the CS5490 energy measurement ICs can all be evaluated with the CDB5484-U, CDB5480-U and CDB5490-U demonstration boards. These CDBs expedite a preliminary performance assessment. Shunt resistors, current transformers or Rogowski coils can be connected to the analog inputs, while intuitive GUI software provides easy and full access to the on-board CS5484/80/90 devices and MCU.
