CLC401 Fast Settling, Wideband High Gain Monolithic Op Amp General Description Features 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 Figure 1 and Figure 2). However, an understanding of the topology will aid in achieving the best performance. The discussion below will proceed for the noninverting gain configuration with the inverting mode analysis being very similar.
