Overview
The ADUC814BRUZ-REEL7, produced by Analog Devices Inc., is a fully integrated 12-bit data acquisition system-on-a-chip. This MicroConverter® device combines a high-performance multichannel analog-to-digital converter (ADC), an 8-bit microcontroller (MCU), and program/data Flash/EE memory on a single chip. It operates from a 3V or 5V power supply and is available in a 28-pin Thin Shrink Small Outline (TSSOP) package. The device is designed for low power consumption and features a high-speed ADC with 247 kSPS and 12-bit resolution, along with dual 12-bit digital-to-analog converters (DACs).
