MICROCIRCUIT DATA SHEET

MNLMH6628-X-RH REV 0A0

Original Creation Date: 04/29/03

Last Update Date: 05/13/03

Last Major Revision Date:

DUAL WIDEBAND, LOW-NOISE, VOLTAGE FEEDBACK OP AMP,

GUARANTEED TO 300k rd(Si) TESTED TO MIL-STD-883,

METHOD 1019

General Description

The National 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 very wide dynamic

range op amp that operates from a single (5 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/SqRtHz). Low 2nd/3rd harmonic distortion (-65/-74dBc

at 10MHz) makes 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 National's VIP 10 (TM) comlimentary bipolar process.
