LMH6628 Dual Wideband, Low Noise, Voltage Feedback Op Amp
January 2003
LMH6628 Dual Wideband, Low Noise, Voltage Feedback Op Amp
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 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 ). Low 2nd/3rd harmonic distortion (-65/ density (2nV/ -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 National's VIP10TM complimentary 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 specific performance is not guaranteed. For guaranteed specifications, see the Electrical Characteristics tables. Note 2: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ > TA. See Note 6 for information on temperature de-rating of this device." Min/Max ratings are based on product characterization and simulation. Individual parameters are tested as noted. 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, 1.5k in series with 100pF. Machine model, 0 In series with 200pF. Note 5: The maximum power dissipation is a function of TJ(MAX), JA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX)-TA)/ JA. All numbers apply for packages soldered directly onto a PC board.
