Description

The CLC5801 is a low-cost, wideband voltage feedback amplifier excellent for low noise applications. It combines a wide bandwidth of 420MHz with very low noise (2n Hz, 1.8pA Hz)and low DC errors (100µV VOS) making it an excellent precision high speed op amp offering closed-loop gains of 10.

The CLC5801 employs a traditional voltage-feedback topology and provides all the benefits of balanced inputs, such as low offsets and drifts, as well as 96dB open-loop gain, 95dB CMRR and a 90dB PSRR. Providing a wide 420MHz bandwidth at a gain of AV = 10, a fast 300V/µs slew rate, the CLC5801 is well suited for wide band active filters and low noise loop filters for PLLs.

The low noise, wide gain-bandwidth, high slew rate and low DC errors enable applications such as medical diagnostic ultrasound, magnetic tape and disk storage, communications and optoelectronics that require maximum high-frequency signal-to-noise ratios. Low noise and offset make theCLC5801 and ideal preamplifier for CD-ROMs and receivers.

The CLC5801 consumes 16mA of supply current and can be used in either dual 5V systems or single supply applications. It can easily drive a 100W load to within 1.6V of either rail. The CLC5801 is available in both SOIC-8 and the tiny SOT23-5.
