Analog Devices, Inc. rozšíril ponuku precíznych analógových mikrokontrolérov ADuC o ďaľšie tri kúsky.
Ide o ADuC7023, ADuC7060 a ADuC7061.


Rodina MCU ADuC7xxx obsahuje ARM7TDMI® jadro, pričom sa ďalej líšia analógovým vybavením.
ADuC7023 využíva 12-bitové analógové periférie (ADC, DAC)
ADuC706x sú som svojím 8kSPS, 24-bitovým, viackanálovým sigma-delta (Σ-Δ) AD prevodníkom, určené na meranie a zber dát.
