General Description
The CLC425 combines a wide bandwidth (
1.9GHz GBW
) with very
low input noise (
1.05nV/
√
Hz, 1.6pA/
√
Hz
) and low dc errors (
100
μ
V
V
OS
, 2
μ
V/°C drift
) to provide a very precise, wide dynamic-range
op amp offering closed-loop gains of
≥
10.
Singularly suited for very wideband high-gain operation, the CLC425
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.
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.
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.
