Norwood, Mass. − Analog Devices, Inc. (ADI) recently launched a mixed-signal control processor that claims to integrate the industry's only embedded dual 16-bit A/D converter with up to 14 bits of accuracy together with a 240-MHz floating-point ARM Cortex-M4 processor core. The ADSP-CM40x devices are aimed at improving the energy efficiency and performance of equipment manufacturers that require highly accurate, closed-loop control in servo, motor-drive, solar photo-voltaic (PV) inverter and other embedded industrial applications.
ADI said the ADSP-CM40x series is the first of a new generation of mixed-signal control processors being developed by the company for precision control applications. In addition to its analog conversion performance and 380-ns conversion speeds, other features include a full sinc filter implementation to interface directly to isolated sigma-delta modulators (AD7400A/AD7401A) which are used in shunt-based current sensing system architectures. The availability of an on-chip sinc filter eliminates the cost and engineering resources required to implement that function in an FPGA, said ADI.
A few key reasons cited by Analog Devices for the development include demand for higher levels of factory automation, which is driving the need for increased industrial-motor power efficiency and performance, as well as solar power set to become the fastest growing source of renewable energy over the next decade.
