Dual Wideband, Low Noise, Voltage Feedback Op Amp
General Description
The National LMH6628 is a high speed dual op amp that of-
fers 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 (±5V) power supply.
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 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 VIP10 ™ compli-
mentary bipolar process.
To reduce design times and assist in board layout, the
LMH6628 is supported by an evaluation board (CLC730036).
