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 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 and ). 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.
