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 (A_V = 2V/V, V_O = 2V_PP), 10-bit distortion levels through 60MHz (R_L = 100Ω), 1.83nV/Hz 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 VIP10™ complimentary bipolar process and National's proven current feedback architecture. The LMH6702 is available in SOIC and SOT23-5 packages.
