CLC401
Fast Settling, Wideband High Gain Monolithic Op Amp
General Description
The CLC401 is a wideband, fast settling op amp designed
for applications requiring gains greater than ±7. Constructed
using an advanced complementary bipolar process and a
proprietary design, the CLC401 features dynamic perfor-
mance far beyond that of typical high speed monolithic op
amps. For example, at a gain of +20, the 3dB bandwidth is
150MHz and the rise/fall time is only 2.5ns.
The wide bandwidth and linear phase (0.2 deviation from
linear at 50MHz) and a very flat gain response makes the
CLC401 ideal for many digital communication system appli-
cations. For example, demodulators need both DC coupling
and high frequency amplification-requirements that are ordi-
narily difficult to meet.
The very fast 10ns settling to 0.1% and the ability to drive
capacitive loads lend themselves well to flash A/D applica-
tions. Systems employing D/A converters also benefit from
the settling time and also by the fact that current-to-voltage
transimpedance amplification is easily accomplished.
The CLC401 provides a quick, effective design solution. Its
stable operation over the entire ±7to ±50 gain range pre-
cludes the need for external compensation. And, unlike
many other high speed-op amps, the CLC401’s power dis-
sipation of 150mW is compatible with designs which must
limit total power dissipation or power supply requirements.
The CLC401 is based on National’s proprietary op amp
topology that uses current feedback instead of the usual
voltage feedback. This unique design has many advantages
over conventional designs (such as settling time that is
relatively independent of gain), yet it is used in basically the
same way (see the gain equations in
Figure 1 and Figure 2).
However, an understanding of the topology will aid in achiev-
ing the best performance. The discussion below will proceed
for the non-inverting gain configuration with the inverting
mode analysis being very similar.
