Santa Clara, Calif. - National Semiconductor Corp. launched its LM7372-a dual line driver designed to drive twisted-pair applications such as ADSL Lite, ADSL Customer Premise Equipment and other xDSL applications, such as VDSL and HDSL-at the Electronica show in Munich last week.
The device is available in a 4 x 4-mm leadless leadframe package (LLP-8) and can deliver 150 milliamperes from 10- to 30-volt supplies.
It features 125-MHz small-signal bandwidth and 700-V /microsecond slew rates in a dual plus/minus 5-V system, while drawing quiescent current of 6.5 mA per channel. Total harmonic distortion is -80 dBc, differential phase is 0.01 and differential gain is 0.02.
In a dual plus/minus 15-V system with 220-MHz bandwidth and 3,000-V/microseconds slew rates, the LM7372 can drive 22 V peak-to-peak from 30-V supplies while delivering 150 mA.
The LM-7372 is priced at $1.98 in 1,000-unit quantities.
