CLC417

CLC417 Dual Low-Power, Programmable Gain Buffer September 1998 N 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 www.DataSheet4U.com 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 6MΩ input impedance along with its exceptionally low 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/µs slew rate also make the CLC417 a perfect choice in cost-sensitive applications such as video monitors, fax machines, copiers, and CATV systems. Back-terminated video applications will be enhanced by a gain of +2 configuration which requires no external gain components reducing costs and board space.
