DESCRIPTION
The CLC425 combines a wide bandwidth (1.9GBW)
with a very low input noise (1.05nV/√Hz, 1.6pA/√Hz)
and low dc errors (100µV V_OS, 2µV/°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 combination of ultra low noise, wide
gain bandwidth, 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.
