	Title:	New Dual Digital-to-Analog Converter for Wideband Communication ( 1146)
	Summary	AD974x and AD978x digital-to-analog converter families feature fast throughput, low noise and a direct RF conversion option to increase dynamic range and reduce distortion levels in wideband communications systems
	Main Text	The AD974x and AD978x families are the latest additions to Analog Devices^ TxDAC(R) portfolio of digital-to-analog converters (DACs) optimized for the transmit signal path of communications systems. The new two-channel, high-speed DACs include the AD974x family of 8-, 10,-, 12-, 14-, and 16-bit devices with sample rates up to 250 MSPS (million samples per second) using LVCMOS (low-voltage CMOS) inputs; and the AD978x family of 12-, 14-, and 16-bit DACs, which use LVDS (low-voltage differential signaling) inputs to achieve sample rates as fast as 600 MSPS. Both families of TxDAC devices feature low noise and low intermodulation distortion to enable the high-quality synthesis of wideband cellular signals.
