General Description

The CLC5654 is a quad, current feedback operational amplifier

that is perfect for many cost-sensitive applications that require

high performance. This device also offers excellent economy

in board space and power, consuming only 5mA per amplifier

while providing 70mA of output current capability. 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 CLC5654 and the low channel-to-

channel crosstalk of 70dB at 5MHz.

The CLC5654 provides excellent performance for video

applications.

Differential gain and phase of 0.03% and 0.03°

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

CLC5654 offers superior dynamic performance with a small

signal bandwidth of 450MHz and slew rate of 2000V/

µs. These

attributes are well suited for many component video applications

such as driving RGB signals down significant lengths of cable.

These and many other application can also take advantage of the

0.1dB flatness to 40MHz.

Combining wide bandwidth with low cost makes the the CLC5654

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.
