CLC5654
Very High-Speed, Low-Cost, Quad Operational Amplifier
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.
