CLC425

CLC425 Ultra Low Noise Wideband Op Amp June 1999 N CLC425 Ultra Low Noise Wideband Op Amp 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 (100µ V VOS, 2µ 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-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. The CLC425 is available in the following versions: CLC425AJP CLC425AJE CLC425A8B -40°C to +85°C -40°C to +85°C -55°C to +125°C 8-pin PDIP 8-pin SOIC 8-pin CERDIP, MIL-STD-883, Level B dice dice, MIL-STD-883, Level B 5-pin SOT Vol...
