LMH6702 Ultra Low Distortion, Wideband Op Amp
June 2003
LMH6702 Ultra Low Distortion, Wideband Op Amp
General Description
The LMH6702 is a very wideband, DC coupled monolithic operational amplifier designed specifically for wide dynamic range systems requiring exceptional signal fidelity. Benefiting from National's current feedback architecture, the LMH6702 offers unity gain stability at exceptional speed without need for external compensation. With its 720MHz bandwidth (AV = 2V/V, VO = 2VPP), 10-bit distortion levels through 60MHz (RL = 100), 1.83nV/ input referred noise and 12.5mA supply current, the LMH6702 is the ideal driver or buffer for high-speed flash A/D and D/A converters. Wide dynamic range systems such as radar and communication receivers, requiring a wideband amplifier offering exceptional signal purity, will find the LMH6702's low input referred noise and low harmonic and intermodulation distortion make it an attractive high speed solution. The LMH6702 is constructed using National's VIP10TM complimentary bipolar process and National's proven current feedback architecture. The LMH6702 is available in SOIC and SOT23-5 packages.

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. Min/Max ratings are based on production testing unless otherwise specified. Note 3: The maximum output current (IOUT) is determined by device power dissipation limitations. Note 4: Human body model: 1.5k in series with 100pF. Machine model: 0 in series with 200pF. Note 5: Slew Rate is the average of the rising and falling edges. Note 6: Typical numbers are the most likely parametric norm. Bold numbers refer to over temperature limits. Note 7: Negative input current implies current flowing out of the device. Note 8: Drift determined by dividing the change in parameter at temperature extremes by the total temperature change. Note 9: Harmonic distortion is strongly influenced by package type (SOT23-5 or SOIC). See Application Note section under "Harmonic Distortion" for more information.
