LMH6628
Dual Wideband, Low Noise, Voltage Feedback Op Amp
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 wide dynamic range op amp that operates from a single
(5V to 12V) or dual (
Each of the LMH6628’s closely matched channels provides
a 300MHz unity gain bandwidth and low input voltage noise
density (2nV/
−74dBc at 10MHz) make the LMH6628 a perfect wide dy-
namic 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 8-pin SOIC package
reduces cost and board space for many composite amplifier
applications such as active filters, differential line drivers/
receivers, fast peak detectors and instrumentation amplifi-
ers.
The LMH6628 is fabricated using National’s VIP10
plimentary bipolar process.
