LMH6702
Ultra Low Distortion, Wideband Op Amp
General Description
The LMH6702 is a very wideband, DC coupled monolithic
operational amplifier designed specifically for wide dynamic
range systems requiring exceptional signal fidelity. Benefit-
ing 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/
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 communi-
cation receivers, requiring a wideband amplifier offering ex-
ceptional signal purity, will find the LMH6702’s low input
referred noise and low harmonic and intermodulation distor-
tion make it an attractive high speed solution.
The LMH6702 is constructed using National’s VIP10™ com-
plimentary bipolar process and National’s proven current
feedback architecture. The LMH6702 is available in SOIC
and SOT23-5 packages.
