CLC409
Very Wideband, Low Distortion Monolithic Op Amp
General Description
The CLC409 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
CLC409 offers a gain range of
±
1 to
±
10 while providing
stable, oscillation free operation without external compensa-
tion, even at unity gain.
With its 350MHz small signal bandwidth (V
OUT
= 2V
PP
),
10-bit distortion levels through 20MHz (R
L
= 100
), 8-bit
distortion levels through 60MHz, 2.2nV/
input referred
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 communi-
cation receivers requiring a wideband amplifier offering ex-
ceptional signal purity will find the CLC409’s low input re-
ferred noise and low harmonic and intermodulation distortion
make it an attractive high speed solution.
Constructed using an advanced, complimentary bipolar pro-
cess and
National’s
proven current feedback architecture,
the CLC409 is available in several versions to meet a variety
of requirements.
