AD7774KP

ADCs/DACs - Special Purpose Overview

The AD7774KP is a high-performance, low-cost CMOS analog I/O port manufactured by Analog Devices Inc. It integrates four 12-bit, 50 MSPS analog-to-digital converters (ADCs) and four 16-bit digital-to-analog converters (DACs) on a single chip. The device utilizes a sigma-delta architecture for the ADCs and a current-steering architecture for the DACs. It operates with a single 3.3 V supply and features a flexible serial interface compatible with SPI, QSPI, and MICROWIRE standards. The component is housed in a 64-lead LFCSP package, designed for applications requiring simultaneous multi-channel signal acquisition and generation.
