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.

In the latest ARM Cortex™-M3 processor family:

  • 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.
  • The ADuCM350 is a complete, coin cell powered, high precision, data acquisition system with fully integrated 160KSPS 16-bit SAR ADC and hardware accelerators to allow for waveform generation and DFT capability. The ADuCM350 is designed for high precision potentiostat, current, voltage, and impedance measurement capabilities. It is based on a 32-bit 16MHz ARM Cortex™-M3 processor.
  • The ADuCRF101 is a fully integrated, data acquisition solution that is designed for low power, wireless applications. It features a 12-bit analog-to-digital converter (ADC), a low power ARM Cortex™-M3 processor, a 862 MHz to 928 MHz and 431 MHz to 464 MHz RF transceiver, and Flash®/EE 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.

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