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/
μ
s, bandwidth of 90MHz (A
v
= +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 0.1dB 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.
The large voltage swing (28V
pp
), continuous output current
(85mA) and slew rate (1800V/
μ
s) 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.
