3 Description

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.
