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

stable, oscillation free operation without external compensa-

tion, even at unity gain.

With its 350MHz small signal bandwidth (V

10-bit distortion levels through 20MHz (R

Ω), 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.
