The ADuC834 is a complete smart transducer front end, integrating two high resolution ADCs, an 8-bit MCU, and program/data Flash/EE memory on a single chip.
The ADuC834 MicroConverter integrates two high‑resolution ADCs (16‑bit and 24‑bit), an 8052‑compatible MCU core, and on‑chip flash/program memory. It targets intelligent sensor, data‑logging, and precision monitoring applications.
The device operates from 3 V or 5 V supplies, offers up to 26 programmable I/O lines, multiple timers, UART/SPI/I²C interfaces, and on‑chip DACs and temperature sensor, making it a versatile solution for embedded instrumentation.
