LMH6628QML Dual Wideband, Low Noise, Voltage Feedback Op Amp Literature Number: SNOSAQ1A

July 12, 2011 Dual Wideband, Low Noise, Voltage Feedback Op Amp General Description The National LMH6628 is a high speed dual op amp that of- fers 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/ ). Low 2nd/3rd harmonic distortion (−65/ −74dBc at 10MHz) make the LMH6628 a perfect wide dy- namic 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 VIP10™ compli- mentary bipolar process. To reduce design times and assist in board layout, the LMH6628 is supported by an evaluation board (CLC730036).

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/ θJA or the number given in the Absolute Maximum Ratings, whichever is lower. Note 3: Output is short circuit protected to ground, however maximum reliability is obtained if output current does not exceed 160mA. Note 4: Human body model, 1.5kΩ in series with 100pF. Note 5: If not tested, shall be guaranteed to the limits specified in table 1 Note 6: Group A testing only. Note 7: Pre and post irradiation limits are identical to those listed under electrical characteristics. These parts may be dose rate sensitive in a space environment and demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters are guaranteed only for the conditions as specified in MIL- STD-883, Method 1019.
