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/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 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/s) provide high-fidelity signal
conditioning for applications such as CCDs, transmission
lines and low impedance circuits. Even driving loads of
100
, 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,
differential-to-single-ended drivers, DAC transimpedance
amplifiers and MOSFET drivers.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation.
Note 2: Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined
from tested parameters.
Note 3: AJ-level: spec. is 100% tested at +25C.
Note 4: Output is short circuit protected to ground, however maximum reliability is obtained if output current does not exceed 125mA.
