DUAL WIDEBAND, LOW-NOISE, VOLTAGE FEEDBACK OP AMP,
GUARANTEED TO 300k rd(Si) TESTED TO MIL-STD-883,
METHOD 1019
General Description
The National LMH6628 is a high speed dual op amp that offers a traditional voltage
feedback topology featuring unity-gain stability and slew-enhanced circuitry. The
LMH6628's low noise and very low harmonic distortion combine to form a very wide dynamic
range op amp that operates from a single (5 to 12V) or dual (+5V) power supply.
Each of the LMH6628's closely matched channels provides a 300MHz unity gain bandwidth and
low input voltage noise density (2nV/SqRtHz). Low 2nd/3rd harmonic distortion (-65/-74dBc
at 10MHz) makes the LMH6628 a perfect wide dynamic-range amplifier for matched I/Q
channels.
With its fast and accurate settling (12ns to 0.1%), the LMH6628 is also an excellent
choice for wide dynamic range, anti-aliasing filters to buffer the inputs of hi resolution
analog-to-digital converters. Combining the LMH6628's two tightly matched amplifiers in a
single package reduces cost and board space for many composite amplifier applications such
as active filters, differential line drivers/receivers, fast peak detectors and
instrumentation amplifiers.
The LMH6628 is fabricated using National's VIP 10 (TM) comlimentary bipolar process.

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 do not guarantee specific performance limits. For guaranteed
specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed. Some performance
characteristics may degrade when the device is not operated under the listed test
conditions.
The maximum power dissipation must be derated at elevated temperatures and is
dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to
ambient thermal resistance), and TA (ambient temperatuer). The maximum allowable
power dissipation at any temperatuer is Pdmax = (Tjmax -TA) / ThetaJA or the number
given in the Absoulute Maximum Ratings, whichever is lower.
Output is short circuit protected to ground, however maximum reliability is obtained
if output current does not exceed 160mA.
