General Description

The CLC5665 is a low-cost, wideband amplifier that provides very

low 2nd and 3rd harmonic distortion at 1MHz (-89/-92dBc). The

great slew rate of 1800V/

µs, bandwidth of 90MHz (A

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 0.1dB bandwidth to 20MHz

and differential gain/phase of 0.05%/0.05° make the CLC5665

the preferred component for broadcast quality NTSC and PAL

video systems.

(85mA) and slew rate (1800V/

µs) provide high-fidelity signal

conditioning for applications such as CCDs, transmission lines

and low impedance circuits.

xDSL, video distribution, multimedia and general purpose

applications will benefit from the CLC5665’s wide bandwidth and

disable feature. Power is reduced and the output becomes 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.
