CLC5644
Low Power, Low Cost, Quad Operational Amplifier
General Description
The CLC5644 is a quad, current feedback operational am-
plifier 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 Band-
width 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 ap-
plications. Differential gain and phase of 0.04% and 0.07˚
makes this device well suited for many professional compos-
ite 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 perfor-
mance with a small signal bandwidth of 170MHz and slew
rate of 1000V/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
applications can also take advantage of the 0.1dB flatness to
25MHz.
Combining wide bandwidth with low cost makes 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 am-
plifier 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 literature on active
filters and a list of these publications can be found on the last
page of this datasheet.
