Product Introduction

Overview

The AD9778ABSVZ is a dual, 14-bit, high dynamic range digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD9776A/AD9778A/AD9779A family, which offers sample rates of up to 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 ADL537x FMOD series from Analog Devices, Inc.
