3 Description
The LMH6702-MIL 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-MIL 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-MIL 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-MIL an
attractive high speed solution.
The LMH6702-MIL is constructed using VIP10™
complimentary bipolar process and proven current
feedback architecture. The LMH6702-MIL is available
in SOIC and SOT-23 packages.
