General DescriptionThe LMH6672isa low cost, dual high speedop amp capable driving signalsto within1Vof the power supply rails.It
featuresthe high output drive with low distortion requiredfor
the demanding applicationofa single supply xDSL line
driver.
When connectedasa differential output driver,the LMH6672
can drivea 50Ω loadto 16.8 VPP swing with only −98 dBc
distortion, fully supporting the peak upstream power levels
for upstream full-rate ADSL. The LMH6672is fully specified
for operation with5V and 12V supplies. Idealfor PCI modem
cards and xDSL modems.
Applications ADSL PCI modem cards xDSL external modems Line drivers
