1.7 GHz, 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. Benefiting
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/ in-
put 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.
