Overview
The AD9776ABSVZRL, produced by Analog Devices Inc., is a dual, 12-bit, high dynamic range digital-to-analog converter (DAC) designed for high-performance applications. This DAC offers a sample rate of 1 GSPS, enabling multicarrier generation up to the Nyquist frequency. It is optimized for direct conversion transmission applications, including complex digital modulation and gain and offset compensation. The device is manufactured on an advanced 0.18 μm CMOS process and operates on 1.8 V and 3.3 V supplies, with a total power consumption of 1.0 W. It is packaged in a 100-lead thin quad flat package (TQFP).
