CLC431/432
Dual Wideband Monolithic Op Amp with Disable
General Description
The CLC431 and CLC432 current-feedback amplifiers pro-
vide wide bandwidths and high slew rates for applications
where board density and power are key considerations.
These amplifiers provide DC-coupled small signal band-
widths exceeding 92MHz while consuming only 7mA per
channel. Operating from
±
15V supplies, the CLC431/432’s
enhanced slew rate circuitry delivers large-signal band-
widths without out voltage swings up to 28V
pp
. A wide range
of bandwidth insensitive gains are made possible by virtue of
the CLC431 and CLC432’s current-feedback topology.
The large common-mode input range and fast settling time
(70ns to 0.05%) make these amplifiers well suited for CCD &
data telecommunication applications. The disable of the
CLC431 can accommodate ECL or TTL logic levels or a wide
range of user definable inputs. With its fast enable/disable
time (0.2µs/1µs) and high channel isolation of 70dB at
10MHz, the CLC431 can easily be configured as a 2:1 MUX.
Many high performance video applications requiring signal
gain and/or switching will be satisfied with the CLC431/432
due to their very low differential gain and phase errors (less
than 0.1% and 0.1˚; A
V
= +2V/V at 4.43MHz into 150Ω load).
Quick 8ns rise and fall times on 10V pulses allow the
CLC431/432 to drive either twisted pair or coaxial transmis-
sion lines over long distances.
The CLC431/432’s combination of low input voltage noise,
wide common-mode input voltage range and large output
voltage swings make them especially well suited for wide
dynamic range signal processing applications
