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 (A_V = 2 V/V, V_O = 2 V_PP),
10-bit distortion levels through 60-MHz (R_L = 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.
