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

Features

(T_A= 25˚C, V_S

5V, R_L= 100Ω Typical unless specified).

n 420MHz, −3dB bandwidth (A_V= 10)

n 2nV/

n 1.8pA/

input voltage noise

input current 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.

n 100µV input offset voltage

n 300V/µs slew rate

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.

n 16mA supply current

n 18ns settling time

Applications

n Ultrasound preamplifier

n CD-ROM preamplifer

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.

n Photo-diode transimpedance amplifier

n Low-noise loop filters for PLLs

n High-performance receivers

n ADC preamplifier

Equivalent Input Noise

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.
