General DescriptionThe CLC449 is an ultra-high-speed monolithic op amp, with a typ-
ical -3dB bandwidth of 1.1GHz at a gain of +2. This wideband op
amp supports rise and fall times less than 1ns, settling time of 6ns
(to 0.2%) and slew rate of 2500V/ms. The CLC449 achieves 2nd
harmonic distortion of -68dBc at 5MHz at a low supply current of
only 12mA. These performance advantages have been achieved
through improvements in National’s proven current feedback
topology combined with a high-speed complementary bipolar
process.
The DC to 1.2GHz bandwidth of the CLC449 is suitable for many IF
and RF applications as a versatile op amp building block for replace-
ment of AC coupled discrete designs. Operational amplifier
functions such as active filters, gain blocks, differentiation, addition,
subtraction and other signal conditioning functions take full
advantage of the CLC449’s unity-gain stable closed-loop
performance.
The CLC449 performance provides greater headroom for lower
frequency applications such as component video, high-resolution
workstation graphics, and LCD displays. The amplifier’s 0.1dB
gain flatness to beyond 200MHz, plus 0.8ns 2V rise and fall times
are ideal for improved time domain performance. In
addition, the 0.03%/0.02° differential gain/phase performance
allows system flexibility for handling standard NTSC and PAL
signals.
In applications using high-speed flash A/D and D/A converters, the
CLC449 provides the necessary wide bandwidth (1.1GHz), settling
(6ns to 0.2%) and low distortion into 50W loads to improve SFDR.
