DESCRIPTION
The 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 (±5V) power supply.
Each of the LMH6628's closely matched channels
provides a 300MHz unity gain bandwidth and low
input voltage noise density (2nV/√Hz). Low 2nd/3rd
harmonic distortion (−65/−74dBc at 10MHz) make 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 Texas Instruments'
VIP10 complimentary bipolar process.
To reduce design times and assist in board layout,
the LMH6628 is supported by an evaluation board
(LMH730036).
