June 1, 2004 – Intersil 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 industry's lowest power consumption for conversion of high-speed digital data to high-accuracy analog. Target applications for these DACs include 3G cellular infrastructure, broadband wireless access, satellite communications, high-resolution imaging, medical equipment and test instrumentation.

These new Intersil DACs are fully supported with technical documentation, evaluation platforms, technical support and an exclusive online Test DriveSM 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/
