Product Introduction

Overview

The AD9779ABSVZRL is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the AD9776A/AD9778A/AD9779A family and is designed to provide 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 DAC outputs are designed to interface seamlessly with analog quadrature modulators such as the AD8349. The device operates on 1.8 V and 3.3 V supplies and is manufactured on an advanced 0.18 μm CMOS process.
