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).
