100-lead, exposed paddle TQFP The AD9776A/AD9778A/AD9779A are dual, 12-/14-/16-bit,
high dynamic range digital-to-analog converters (DACs) that
provide a sample rate of 1 GSPS, permitting a multicarrier
generation up to the Nyquist frequency. They include features
optimized for direct conversion transmission applications,
including complex digital modulation and gain and offset
compensation. The DAC outputs are optimized to interface
seamlessly with analog quadrature modulators such as the
