CLC425

Ultra Low Noise Wideband Op Amp

General Description

Features

The CLC425 combines a wide bandwidth (1.9GHz GBW) with very

lowinputnoise(1.05nV/√Hz, 1.6pA/√Hz)andlowdcerrors(100µV

V_OS, 2µV/°C drift) to provide a very precise, wide dynamic-range

op amp offering closed-loop gains of ≥10.

■ 1.9GHz gain-bandwidth product

■ 1.05nV/√Hz input voltage noise

■ 0.8pA/√Hz @ Icc < 5mA

■ 100µV input offset voltage, 2µV/°C drift

■ 350V/µs slew rate

Singularlysuitedforverywidebandhigh-gainoperation,theCLC425

employs a traditional voltage-feedback topology providing all the

benefits of balanced inputs, such as low offsets and drifts, as well

as a 96dB open-loop gain, a 100dB CMRR and a 95dB PSRR.

■ 15mA to 5mA adjustable supply current

■ Gain range ±10 to ±1,000V/V

■ Evaluation boards & simulation

macromodel

■ 0.9dB NF @ R = 700Ω

The CLC425 also offers great flexibility with its externally adjustable

supply current, allowing designers to easily choose the optimum

set of power, bandwidth, noise and distortion performance.

Operating from ±5V power supplies, the CLC425 defaults to a

15mA quiescent current, or by adding one external resistor, the

supply current can be adjusted to less than 5mA.

Applications

■ Instrumentation sense amplifiers

■ Ultrasound pre-amps

■ Magnetic tape & disk pre-amps

■ Photo-diode transimpedance amplifiers

■ Wide band active filters

■ Low noise figure RF amplifiers

■ Professional audio systems

■ Low-noise loop filters for PLLs

The CLC425's combination of ultra-low noise, wide gain-band-

width, high slew rate and low dc errors will enable applications in

areas such as medical diagnostic ultrasound, magnetic tape & disk

storage, communications and opto-electronics to achieve maximum

high-frequency signal-to-noise ratios.
