Overview
The AD9736BBCZ is a high-performance, 14-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD973x family, which includes the AD9734 and AD9735, offering different resolutions. The AD9736 is designed for high-frequency applications, supporting sample rates up to 1200 MSPS, making it suitable for multicarrier generation and various high-speed signal processing tasks.
The device features a serial peripheral interface (SPI) for programming internal parameters and reading status registers. It also includes a reduced-specification LVDS interface to achieve high sample rates and supports double data rate (DDR) LVDS data receivers. The AD9736 is manufactured on a 0.18 µm CMOS process and operates from dual 1.8V and 3.3V power supplies, ensuring low power consumption and high dynamic performance.
