Overview
The ADUC814BRUZ-REEL, 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 on-chip Flash and EEPROM memory. The ADUC814 operates from a 32 kHz crystal with an on-chip phase-locked loop (PLL) generating a high-frequency clock of 16.78 MHz. It is designed for low power consumption and is available in a 28-pin TSSOP package, supporting both 3V and 5V power supplies.
