CLC428

Dual Wideband, Low-Noise, Voltage Feedback Op Amp

General Description

Features

TheCLC428isaveryhigh-speeddualopampthatoffersatraditional

voltage-feedback topology featuring unity-gain stability and slew-

enhanced circuitry. The CLC428’s ultra low noise and very low

harmonic distortion combine to form a very wide dynamic-range op

ampthatoperatesfromasingle(5to12V)ordual(±5V)powersupply.

■ Wideunity-gainbandwidth:160MHz

■ Ultra-low noise: 2.0nV/√Hz

■ Low distortion: -78dBc 2nd (2MHz)

-62/-72dBc(10MHz)

■ Settling time: 16ns to 0.1%

■ Supply voltage range: ±2.5 to ±5 or

single supply

EachoftheCLC428’scloselymatchedchannelsprovidesa160MHz

unity-gain bandwidth with an ultra low input voltage noise density

(2nV/√Hz). Verylow2nd/3rdharmonicdistortion(-62/-72dBc)aswell

as high channel-to-channel isolation (-62dB) make the CLC428 a

perfect wide dynamic-range amplifier for matched I/Q channels.

■ High output current: ±80mA

Applications

■ Generalpurposedualopamp

■ Lownoiseintegrators

Withitsfastandaccuratesettling(16nsto0.1%),theCLC428isalso

a excellent choice for wide-dynamic range, anti-aliasing filters

to buffer the inputs of hi-resolution analog-to-digital converters.

Combining the CLC428’s two tightly-matched amplifiers in a single

eight-pin SOIC reduces cost and board space for many composite

amplifier applications such as active filters, differential line drivers/

receivers, fast peak detectors and instrumentation amplifiers.

■ Low noise active filters

■ Diff-in/diff-outinstrumentationamp

■ Driver/receiver for transmission systems

■ High-speeddetectors

■ I/Q channel amplifiers

To reduce design times and assist in board layout, the CLC428 is

supported by an evaluation board and a SPICE simulation model

availablefromNationalSemiconductor.
