Overview
The AD9735BBCZRL is a high-performance, 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This component is part of the AD973x family, which includes the AD9736 (14-bit) and AD9734 (10-bit) models. The AD9735 is designed for high-frequency applications, offering sample rates of up to 1200 MSPS, making it suitable for multicarrier generation up to its Nyquist frequency. It features a serial peripheral interface (SPI) for programming internal parameters and reading status registers, and it utilizes a reduced-specification LVDS interface to achieve high sample rates.
