New 260-MHz DACs Offer High Performance, Low Power

and Single-Supply Operation

Intersil Corporation (Nasdaq:ISIL), a world leader in the design and manufacture of high performance analog solutions, today announced the release of three new high-speed and low-power precision digital-to-analog converters (DACs), the 10-bit ISL5757, the 12-bit ISL5857 and the 14-bit ISL5957. Operating at frequencies as high as 260 million samples per second (Msps), these new converters offer the highest precision, single-supply operation and the industries lowest power consumption for conversion of high-speed digital data to high-accuracy analog. Target applications for these high-performance DACs include 3G cellular infrastructure, broadband wireless access, satellite communications, high-resolution imaging, medical equipment and test instrumentation.

"Intersil's new high-speed ISL5757, ISL5857 and ISL5957 DACs raise the bar on performance and contribute greatly to improving the quality of service for all broadband communications systems and instrumentation," said Michael Althar, vice president of Intersil's Analog Solutions Products. "They offer lower power consumption and single-supply operation as performance upgrades from currently popular DACs used in high-bit and -speed data conversion applications."

These new Intersil DACs are fully supported with technical documentation, evaluation platforms, technical support and an exclusive online Test Drive(SM) service that allows customers to evaluate Intersil's digital-to-analog converters and analog-to-digital converters without the time and expense of utilizing engineering and laboratory resources. This free online service is available to customers at Intersil's Test Drive Web site: http://www.intersil.com/testdrive/
