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 performance 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 applications. For example,
demodulators need both DC coupling and high
frequency amplification-requirements that are
ordinarily 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 applications. 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 ±7 to ±50
gain range precludes the need for external
compensation. And, unlike many other high speed-op
amps, the CLC401's power dissipation of 150mW is
compatible with designs which must limit total power
dissipation or power supply requirements.
The CLC401 is based on TI'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 17 and Figure 18). However, an
understanding of the topology will aid in achieving the
best performance. The discussion below will proceed
for the non-inverting gain configuration with the
inverting mode analysis being very similar.
