LT1794 - Dual 500mA, 200MHz xDSL Line Driver Amplifier

The outputs drive a 100 Ohms load to �11.1V with �12V supplies, and �10.9V with a 250mA load. The LT1794, with its increased swing on lower supplies, can be used to upgrade LT1795 line driver applications.

The LT1794 is available in the very small, thermally enhanced, 20-lead TSSOP for maximum port density in line driver applications. The 20-lead SW is also available.
