CLC417
Dual Low-Power, Programmable Gain Buffer
General Description
The CLC417 is a dual, low-cost, high-speed (120MHz) buffer which
features user-programmable gains of +2, +1, and -1V/V. The
CLC417’s high 60mA output current, coupled with its ultra-low
39mW per channel power consumption makes it the ideal choice for
demanding applications that are sensitive to both power and cost.
Utilizing National’s proven architectures, this dual current feedback
amplifier surpasses the performance of alternate solutions with a
closed-loop design that produces new standards for buffers in gain
accuracy, input impedance, and input bias currents. The CLC417’s
internal feedback network provides an excellent gain accuracy of
0.1%. High source impedance applications will benefit from the
CLC417’s 6M
100nA input bias current.
With exceptional gain flatness and low differential gain and phase
errors, the CLC417 is very useful for professional video processing
and distribution. A 120MHz -3dB bandwidth coupled with a 400V/ s
slew rate also make the CLC417 a perfect choice in cost-sensitive
applications such as video monitors, fax machines, copiers, and
CATV systems.
enhanced by a gain of +2 configuration which requires no external
gain components reducing costs and board space.
