DESCRIPTION
The Texas Instruments 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 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 amplifiers.
The LMH6628 is fabricated using TI’s VIP10™
complimentary bipolar process.
To reduce design times and assist in board layout,
the LMH6628 is supported by an evaluation board
(CLC730036).
