Precision analog functions are combined in Analog Devices Precision Analog Microcontrollers, such as high resolution ADCs and DACs, voltage reference, temperature sensor, and a host of other peripherals, with an industry-standard microcontroller and flash memory. Industrial, instrumentation, medical, communications, and automotive applications has integrated 12-, 16- and 24-bit A/D converters, 12-bit DACs with flash, SRAM, and a host of digital peripherals integrated by the ADuC7xxx ARM7TDMI® group . 12-bit to 24-bit analog precision, in-circuit reprogrammable Flash/EE memory, and an on-chip 8052 core was first integrated by The ADuC8xx series. The ADuCM36x group extends the precision data acquisition systems with the first fully integrated, 4 kSPS, 24-bit data acquisition system incorporating dual, high performance multi-channel sigma-delta (?-?) analog-to-digital converters (ADCs), 32-bit ARM Cortex™. For direct interfacing to external precision sensors in both wired and battery powered applications a M3 processor, and Flash/EE memory on a single chip is designed.
