LMH6672 Dual, High Output Current, High Speed Op Amp
January 2002
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 load to 16.8VPP 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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics. Note 2: Human body model, 1.5k in series with 100pF. Machine model, 200 in series with 100pF. Note 3: Shorting the output to either supply or ground will exceed the absolute maximum TJ and can result in failure. Note 4: The maximum power dissipation is a function of TJ(MAX), JA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) - TA)/JA. All numbers apply for packages soldered directly onto a PC board. Note 5: Typical values represent the most likely parametric norm. Note 6: All limits are guaranteed by testing, characterization or statistical analysis.
