CLC430

General Purpose 100MHz Op Amp with Disable

General Description

The CLC430 is a low-cost, wideband monolithic amplifier for general

purpose applications. The CLC430 utilizes National’s patented

current feedback circuit topology to provide an op amp with a slew rate

of 2000V/

µs, 100MHz unity-gain bandwidth and fast output disable

function. Like all current feedback op amps, the CLC430 allows the

frequency response to be optimized (or adjusted) by the selection of

the feedback resistor. For demanding video applications, the 0.1dB

bandwidth to 20MHz and differential gain/phase of 0.03%/0.05° make

the CLC430 the preferred component for broadcast quality NTSC and

PAL video systems.

and slew rate (2000V/

µs) provide high-fidelity signal conditioning for

applications such as CCDs, transmission lines and low impedance

circuits. Even driving loads of 100

Ω, the CLC430 provides very low

2nd and 3rd harmonic distortion at 1MHz (-76/-82dBc).

Video distribution, multimedia and general purpose applications will

benefit from the CLC430’s wide bandwidth and disable feature. Power

is reduced and the output becomes a high impedance when disabled.

The wide gain range of the CLC430 makes this general purpose op

amp an improved solution for circuits such as active filters, differen-

tial-to-single-ended drivers, DAC transimpedance amplifiers and

MOSFET drivers.
