General 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 tak e
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/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 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.
