May 2001
CLC425 Ultra Low Noise Wideband Op Amp
General Description
The CLC425 combines a wide bandwidth (1.9GBW) with a very low input noise (1.05nV/ , 1.6pA/ ) and low dc errors (100µV VOS, 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's 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.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation. Note 2: Max/min ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined from tested parameters. Note 3: AJ-level: spec. is 100% tested at +25°C, sample at 85°C.
