The ADuC846 is a microcontroller from Analog Devices that integrates high-resolution Sigma-Delta ADCs, a 16-bit processor, and 62kB FLASH flash memory
The ADuC846 is a complete smart transducer front end integrating two high resolution sigma-delta ADCs, an 8051-based microcontroller core, and nonvolatile Flash/EE memory on a single chip. It is designed for applications such as intelligent sensors, weigh scales, portable instrumentation, and data logging.
The device features dual independent 16-bit ADCs with programmable output data rates and digital filtering, suitable for measuring wide dynamic range, low frequency signals like strain-gage or pressure transducer outputs. The microcontroller core offers up to 12.58MIPs performance while maintaining 8051 instruction set compatibility.
