Ultra Low Noise Wideband Op Amp
General Description
The CLC425 combines a wide bandwidth (1.9GBW) with a
very low input noise (1.05nV/
rors (100µV V
dynamic range op amp offering closed-loop gains of
Singularly suited for very wideband high gain operation, the
CLC425 employs a traditional voltage feedback topology pro-
viding 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.
The CLC425 also offers great flexibility with its externally ad-
justable 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.
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.
