The ADuC831 MicroConverter is a fully integrated 12-bit data acquisition system-on-a-chip. Like all of ADI's MicroConverter products, it features precision A/D and D/A conversion and a Flash microcontroller on a single chip.
The ADuC831 is 100% hardware backward compatible with the ADuC812. It is available in 52-pin PQFP or 56-pin CSP packages and operates on a 3V or 5V power supply.
