General Description
The Comlinear CLC407 is a low-cost, high-speed (110MHz)
buffer which features user-programmable gains of +2, +1, and -1
V/V. This high-performance part has the added versatility of a
TTL-compatible disable which quickly switches the buffer off in
18ns and back on in 40ns. The CLC407’s high 60mA output
current, coupled with its ultra-low 35mW power consumption
makes it the ideal choice for demanding applications that are
sensitive to both power and cost.
Utilizing Comlinear’s proven architectures, this 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
CLC407’s internal feedback network provides an excellent gain
accuracy of 0.1%.
High source impedance applications will
benefit from the CLC407’s 6M
Ω input impedance along with its
exceptionally low 100nA input bias current.
With 0.1dB flatness to 30MHz and low differential gain and phase
errors, the CLC407 is very useful for professional video process-
ing and distribution. A 110MHz -3dB bandwidth coupled with a
350V/
µs slew rate also make the CLC407 a perfect choice in
cost-sensitive applications such as video monitors, fax machines,
copiers, and CATV systems. Back-terminated video applications
will especially appreciate +2 gains which require no external gain
components reducing inventory costs and board space.
