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 50

Ω load to 16.8V

PP swing with only −93dBc

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.
