说明

The LMH6702 is a very wideband, DC-coupled monolithic operational amplifier designed specifically for wide dynamic range systems requiring exceptional signal fidelity. Benefitting from current feedback architecture, the LMH6702 offers unity gain stability at exceptional speed without need for external compensation.

With its 720-MHz bandwidth (AV = 2 V/V, VO = 2 VPP), 10-bit distortion levels through 60-MHz (RL = 100 Ω), 1.83-nV/√Hz input referred noise and 12.5-mA 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 that require a wideband amplifier offering exceptional signal purity will find the low input referred noise and low harmonic and intermodulation distortion of the LMH6702 an attractive high speed solution.

The LMH6702 is constructed using VIP10™ complimentary bipolar process and proven current feedback architecture. The LMH6702 is available in SOIC and SOT-23 packages.
