ESD (human body model) 1000V DescriptionThe CLC425 combines a wide bandwidth (1.9GHz GBW) with very low input noise (1.05nV/ÖHz, 1.6pA/ÖHz) and low dc errors (100mV VOS, 2mV/°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.
