This document introduces the MicroConverter® ADuC814 product from Analog Devices. The product is a small package 12-bit ADC with embedded flash MCU. It features a 6-channel 247 kSPS ADC, 12-bit resolution, high-speed data capture mode, etc. In addition, it also has programmable reference and dual voltage output DACs, as well as 8 kbytes on-chip Flash/EE program memory and 640 bytes on-chip Flash/EE data memory, etc.
The ADuC814 is a fully integrated 12‑bit, 247 kSPS MicroConverter that combines an ADC, dual DACs, an 8052‑compatible MCU core, on‑chip Flash/EE memory, and a range of digital peripherals. It operates from a single 3 V or 5 V supply and is housed in a 28‑lead TSSOP package.
The document lists detailed electrical specifications, pin configurations, memory organization, power‑supply requirements, and an ordering guide for the various ADuC814 part numbers. It also includes typical performance curves and design considerations for hardware designers.
