Description

The CLC5644 is a quad, current feedback operational amplifier that is perfect for many cost-sensitive applications that require high performance, especially when power dissipation is critical. Not only does the CLC5644 offer excellent economy in board space, but has an excellent performance vs power tradeoff which yields a 170MHz Small Signal Bandwidth while dissipating only 25mW. Applications requiring significant density of high speed devices such as video routers, matrix switches and high-order active filters will benefit from the configuration of the CLC5644 and the low channel-to-channel crosstalk of 76dB at 1MHz.

The CLC5644 provides excellent performance for video applications. Differential gain and phase of 0.04% and 0.07° makes this device well suited for many professional composite video systems, but consumer applications will also be able to take advantage of these features due to the device's low cost. The CLC5644 offers superior dynamic performance with a small signal bandwidth of 170MHz and slew rate of 1000V/ms. These attributes are well suited for many component video applications such as driving RGB signals down significant lengths of cable. These and many other applications can also take advantage of the 0.1dB flatness to 25MHz.

Combining wide bandwidth with low cost makes the the CLC5644 an attractive option for active filters. SAW filters are often used in IF filters in the 10's of MHz range, but higher order filters designed around a quad operational amplifier may offer an economical alternative to the typical SAW approach and offer greater freedom in the selection of filter parameters. National Semiconductor's Comlinear Products Group has published a wide array of liturature on active filters and a list of these publications can be found on the last page of this datasheet.
