Digital-to-Analog Converter
Analog Devices introduces a 16-bit D/A converter (DAC) to achieve a sample rate of 1 GS/S (giga-samples-per-second). The interpolating dual AD9779 is designed to enable high quality conversion of wireless standards including W-CDMA, CDMA2000, TD-SCDMA, and WiMAX. In addition to the AD9779, Analog Devices introduces the AD9778 and AD9776 dual interpolating DACs, forming a family of 16-/14-/12-bit pin-compatible. The AD9779 offers 4 dB lower noise, 15 dB better intermodulation distortion (IMD), and 20 dB higher spurious free dynamic range (SFDR) at a 70 MHz output frequency while consuming 600 mW of power at 500 MS/S and 1 W at 1 GSPS. The device contains on-chip digital interpolation filters, a complex digital modulator, and a digital mixer.
