Overview
The AD9736BBCZRL, produced by Analog Devices Inc., is a high-performance, high-frequency Digital-to-Analog Converter (DAC) that is part of the AD973x family. This 14-bit DAC is designed to operate at sample rates of up to 1200 MSPS, enabling multicarrier generation up to the Nyquist frequency. The device is manufactured on a 0.18 μm CMOS process and operates from dual 1.8 V and 3.3 V supplies, with a total power consumption of 380 mW in bypass mode. It is packaged in a 160-lead chip scale ball grid array (CSP_BGA) to minimize package parasitics.
