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鈥檚 patented
current feedback circuit topology to provide an op amp with a slew rate
of 2000V/碌s, 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擄 make
the CLC430 the preferred component for broadcast quality NTSC and
PAL video systems.
The large voltage swing (28V
pp
), continuous output current (85mA)
and slew rate (2000V/碌s) provide high-fidelity signal conditioning for
applications such as CCDs, transmission lines and low impedance
circuits. Even driving loads of 100鈩? 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鈥檚 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.
