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).
