Overview
The AD9747BCPZRL is a high-performance, dual 16-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This component is part of the AD9743/AD9745/AD976/AD9747 family, which are pin-compatible and offer various resolutions and sample rates. The AD9747 is specifically designed for high dynamic range applications, particularly in direct conversion transmit scenarios.
It features a proprietary dynamic output architecture that allows for the synthesis of analog outputs even above the Nyquist frequency by shifting energy away from the fundamental and into the image frequency. This DAC is highly versatile and integrates seamlessly with analog quadrature modulators, such as the ADL5370.
