Analog Devices Launches 24-Bit Sigma-Delta ADCs with ARM7 Core for

Analog Devices Inc. has introduced an integrated microcontroller family with data conversion performance for hardware, firmware and industrial systems engineers designing smart sensing, factory automation and instrumentation equipment. Including 3 models, the Series ADuC706x analog MCUs consume 2.6 mA and handle 4-20 mA loop-powered applications in factory automation and precision instruments. Featuring 24-bit sigma-delta ADCs and ARM7 core with 8 interrupt priority levels, units also incorporate 32 Kb of flash memory and 4 Kb of SRAM, programmable gain amplifier, multiplexers, buffers, auxiliary 24-bit ADC for cold junction compensation and interfacing to thermocouple applications, and SPI, UART, and I²C ports. The ADuC706x family is available in sample quantities and will be in full factory production in August 2008. The ADuC7060, ADuC7061 and ADuC7062 precision analog microcontrollers are priced at $4.90, $3.95 and $3.40 respectively, in 1,000-unit quantities.
