FEATURES

DESCRIPTION

The CLC401 is a wideband, fast settling op amp

2

•

−3dB Bandwidth of 150MHz

designed for applications requiring gains greater than

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

the rise/fall time is only 2.5ns.

The wide bandwidth and linear phase (0.2° deviation

The very fast 10ns settling to 0.1% and the ability to

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.
