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 6MW 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 processing and distribution. A 110MHz -3dB bandwidth coupled with a 350V/ms 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.
