The document introduces the features and characteristics of the REV. A a ADuC834 MicroConverter® from Dinghao, including inventory, technical information, encyclopedia information, and hot news.
The ADuC834 is a complete smart‑transducer front‑end that integrates two high‑resolution ADCs (16‑bit and 24‑bit), an 8052‑compatible MCU core, flash/program memory, DACs, and on‑chip peripherals on a single chip. It is intended for intelligent‑sensor applications such as weigh scales, portable instrumentation, and data‑logging systems.
The document provides functional block diagrams, pin‑out tables, electrical specifications, power‑supply requirements, package dimensions (MQFP and LFCSP), and timing information for serial interfaces, enabling designers to implement the device in hardware and firmware.
