CLC5801
High Speed Low Noise Voltage Feedback Amplifier
General 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
(2nV/ , 1.8pA/ ) and low DC errors (100µV V_OS)
making it an excellent precision high speed op amp offering
closed-loop gains of ≥ 10.
The CLC5801 employs a traditional voltage-feedback topol-
ogy 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 band-
width at a gain of A_V = 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 ul-
trasound, magnetic tape and disk storage, communications
and optoelectronics that require maximum high-frequency
signal-to-noise ratios. Low noise and offset make the
CLC5801 and ideal preamplifier for CD-ROMs and receiv-
ers.
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 100Ω load to within 1.6V of either rail.
The CLC5801 is available in both SOIC-8 and the tiny
SOT23-5.
