CLC449
1.1GHz Ultra Wideband Monolithic Op Amp
General Description
The CLC449 is an ultra high speed monolithic op amp, with
a typical −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/µs. 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 replacement 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 step) 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 0.02%) and low
distortion into 50
