Overview
The AD9736BBC, produced by Analog Devices Inc., is a high-performance, 14-bit digital-to-analog converter (DAC) designed for high-frequency applications. It is part of the AD973x family, which includes the AD9735 and AD9734 as 12-bit and 10-bit members, respectively. The AD9736 operates at sample rates of up to 1200 MSPS, enabling multicarrier generation up to their Nyquist frequency. This DAC is manufactured on a 0.18 μm CMOS process and supports dual-supply operation at 1.8 V and 3.3 V, with a total power consumption of 380 mW in bypass mode.
