Data acquisition SoC delivers high accuracy using 1-mA of current
EDN Staff - June 4, 2012
The ADuCM360 is a fully integrated, 4-kSPS, 24-bit data acquisition system-on-a-chip that combines dual, high-performance, multi-channel sigma-delta A/D converters, a 32-bit ARM Cortex M3 MCU and flash/EE memory. Using only 1-mA of operating current, the device directly interfaces to external 4- to 20-mA loop-powered precision sensors in industrial process control, or applications where the second A/D converter is needed for temperature compensation on the sensor, or for dual-sensor applications.
The ADuCM360 incorporates a flexible 11-channel DMA controller supporting wired communication peripherals. The converters can operate in fully differential or single-ended modes. The ADuCM361 version contains all the features of the ADuCM360, but includes only one A/D converter, and will be available in August.
The ADuCM360 is available now, priced at $7.26 (1K units), and is supported by a low-cost ($119) QuickStart Development Kit that includes sample code, function libraries, compilers and emulators for fast and less expensive software development.
