	Title:	New High Speed DACS from Analog Devices ( 1248)
	Summary	Dual-channel transmit DACs use 40 percent less power and are one-third the size of competing devices, yielding power savings in communications, industrial and instrumentation equipment.
	Main Text	Analog Devices is helping electronic equipment manufacturers design more energy-efficient products with the introduction today of eight TxDAC® transmit digital-to-analog converters (DACs), each integrating two DACs on a single device. Adding to ADI’s extensive high-speed DAC portfolio, the new pin-compatible dual TxDAC converters are designed for communications, industrial, instrumentation and other demanding high-performance applications for which low power consumption and space savings yield significant cost, performance and time-to-market advantages. Dissipating only 220 mW at their maximum sample rate, the AD911x series of dual TxDAC devices consume 40 percent less power and are one-third the size of competing transmit DACs, while achieving 10 dB better SFDR (spurious-free dynamic range) performance. The AD971x series of dual TxDAC devices, with 2-mA full-scale output current, are even more energy efficient, consuming 70 percent less power than competing solutions. “With the industry increasingly focused on efficiency and portability, design engineers are being squeezed to reduce power consumption and board space in their designs,” said David Robertson, product line director for the High Speed Signal Processing group, Analog Devices. “Whether they’re designing femtocell base stations, battery-powered instrumentation or medical applications, designers are looking for new DAC products that will help them meet their space and power budgets, without sacrificing performance.”
