Overview
The ADUC814ARU, produced by Analog Devices Inc., is a fully integrated 12-bit data acquisition system-on-a-chip. It combines a high-performance multichannel ADC, an 8-bit MCU based on the 8052 core, and program/data Flash/EE memory on a single chip. This MicroConverter is designed for precision A/D and D/A conversion and is available in a 28-pin TSSOP package. It operates on a single 3V or 5V power supply and is fully specified for operation from -40°C to +125°C.
