CLC425
CLC425 is Ultra Low Noise Wideband Op Amp manufactured by National Semiconductor.
- Part of the CLC comparator family.
- Part of the CLC comparator family.
Description
The CLC425 bines a wide bandwidth (1.9GHz GBW) with very low input noise (1.05n V/√ Hz, 1.6p A/√ 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 96d B open-loop gain, a 100d B CMRR and a 95d B 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 15m A quiescent current, or by adding one external resistor, the supply current can be adjusted to less than 5m A. The CLC425's bination 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, munications 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
