Analog Microcontrollers

Analog Devices Precision Analog Microcontrollers combine precision analog functions, 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. The ADuC7xxx ARM7TDMI® family integrates 12-, 16- and 24-bit A/D converters, 12-bit DACs with flash, SRAM, and a host of digital peripherals designed for industrial, instrumentation, medical, communications, and automotive applications. The ADuC8xx series was the first to integrate true 12-bit to 24-bit analog precision, in-circuit reprogrammable Flash/EE memory, and an on-chip 8052 core. The ADuCM36x family 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 (Σ-Δ) analog-to-digital converters (ADCs), 32-bit ARM Cortex™-M3 processor, and Flash/EE memory on a single chip designed for direct interfacing to external precision sensors in both wired and battery powered applications.

Circuit from the lab Engineered. Tested. Ready to Integrate.
