CLC409
Very Wideband, Low Distortion Monolithic Op Amp
General Description
Features
The CLC409 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
CLC409 offers a gain range of ± 1 to ± 10 while providing
stable, oscillation free operation without external compensation, even at unity gain.
With its 350MHz small signal bandwidth (VOUT = 2VPP),
10-bit distortion levels through 20MHz (RL = 100Ω), 8-bit
input referred
distortion levels through 60MHz, 2.2nV/
noise and 13.5mA supply current, the CLC409 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 requiring a wideband amplifier offering exceptional signal purity will find the CLC409’s low input referred noise and low harmonic and intermodulation distortion
make it an attractive high speed solution.
Constructed using an advanced, complimentary bipolar process and National’s proven current feedback architecture,
the CLC409 is available in several versions to meet a variety
of requirements.
