CLC400  Product Folder

The CLC400 is a high speed, fast setting operational amplifier designed for low gain applications. Constructed using a unique, proprietary design and an advanced complementary bipolar process, the CLC400 offers performance far beyond that normally offered by ordinary monolithic op amps. In addition, unlike many other high speed op amps the CLC400 offers both high performance and stability without the need for compensation circuitry - even at a gain of +1.

The fast 12ns settling to 0.05% and its ability to drive capacitive loads makes the CLC400 an ideal flash A/D driver. The wide bandwidth of 200MHz and the very linear phase ensure unsurpassed signal fidelity. Systems employing digital to analog converters also benefit from the use of the CLC400 - especially if linearity and drive levels are important to system performance.

The CLC400 provides a simple, high performance solution for video distribution and line driving applications. The 50mA output current and guaranteed specifications for 100 loads provide ample drive capability and assured performance.

The CLC400 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 following discussion will proceed for the non-inverting gain configuration with the inverting mode analysis being very similar.
