CLC5665 Datasheet | National Semiconductor

Description The CLC5665 is a low-cost, wideband amplifier that provides very low 2nd and 3rd harmonic distortion at 1MHz (-89/-92d Bc). The great slew rate of 1800V/µs, bandwidth of 90MHz (Av = +1) and fast disable make it an excellent choice for many high speed multiplexing applications. Like all current feedback op amps, the CLC5665 allows the frequency response to be optimized (or adjusted) by the selection of the feedback resistor. For demanding video applications, the 0.1d B bandwidth to 20MHz and differential gain/phase of 0.05%/0.05° make the CLC5665 the preferred ponent for broadcast quality NTSC and PAL video systems. The large voltage swing (28Vpp), continuous output current (85m A) and slew rate (1800V/µs) provide high-fidelity signal conditioning for applications such as CCDs, transmission lines and low impedance circuits. x DSL, video distribution, multimedia and general purpose applications will benefit from the CLC5665’s wide bandwidth and disable feature . Power is reduced and the output bees a high impedance when disabled. The wide gain range of the CLC5665 makes this general purpose op amp an improved solution for circuits such as active filters, single-to-differential-ended drivers, DAC transimpedance amplifiers and MOSFET drivers.
