LMH6672
Dual, High Output Current, High Speed Op Amp
General Description
The LMH6672 is a low cost, dual high speed op amp capable
of driving signals to within 1V of the power supply rails. It
features the high output drive with low distortion required for
the demanding application of a single supply xDSL line
driver.
When connected as a differential output driver, the LMH6672
can drive a 50Ω load to 16.8 V
distortion, fully supporting the peak upstream power levels
for upstream full-rate ADSL. The LMH6672 is fully specified
for operation with 5V and 12V supplies. Ideal for PCI modem
cards and xDSL modems.
Applications
n ADSL PCI modem cards
n xDSL external modems
n Line drivers
