ADuC814 is a 12-bit ADC chip launched by Analog Devices, which integrates Flash MCU, has 6-channel 247 kSPS ADC, 12-bit resolution, high precision data acquisition mode, programmable reference and dual voltage output DACs
The ADuC814 is a fully integrated 247 kSPS, 12-bit data acquisition system incorporating a high performance multichannel ADC, an 8-bit MCU, and program/data Flash/EE memory on a single chip. This low power device operates from a 32 kHz crystal with an on-chip PLL generating a high frequency clock of 16.78 MHz. It includes features such as a 12-bit ADC, dual voltage output DACs, nonvolatile Flash/EE memory, and various on-chip peripherals.
The document provides comprehensive specifications for the ADC and DAC channels, including DC accuracy, dynamic performance, and input/output voltage ranges. It also covers the architecture, memory organization, and detailed descriptions of on-chip peripherals such as timers, UART, SPI, and the watchdog timer, along with hardware design considerations and timing specifications.
