24bit sigma-delta ADCS paired with ARM7 core
20 June 2008
A family of microcontrollers for hardware, firmware and industrial systems engineers designing smart sensing, factory automation and instrumentation equipment has been launched.
The ADuC706x from Analog Devices incorporate two 24bit sigma-delta ADCs and other analogue peripherals with a 32bit ARM7 core for precision sensing applications.
Comprising of the ADuC7060, ADuC7061 and ADuC7062, the range has been designed for 4mA – 20mA loop-powered applications in factory automation and precision instruments and features an ADC noise performance of 60nV.
In addition to the 24bit sigma-delta ADCs and ARM7 core with eight interrupt priority levels, the new microcontrollers incorporate 32Kbyte of flash memory and 4Kbyte of SRAM. There is also a programmable gain amplifier, multiplexers, buffers, an auxiliary 24bit ADC for cold junction compensation and interfacing to thermocouple applications, and SPI (serial peripheral interface), UART (universal asynchronous receivers-transmitters) and I²C ports. The devices consume 2.6mA with all peripherals activated.
The ADuC7060 is available in a 7mm x 7mm 48pin chip-scale (QFN) package. The other two models come in a 5mm x 5mm 32pin chip-scale (QFN) packages, but the ADuC7062 does not include the auxiliary ADC channel.
