CLC415
Quad, Wideband Monolithic Op Amp
General Description
Features
The CLC415 is a wideband, quad, monolithic operational
amplifier designed for intermediate gain applications where
power and cost per channel of are primary concern. Benefiting from National’s current feedback architecture, the
CLC415 offers a gain range of ± 1 to ± 10 while providing
stable, oscillation free operation without external compensation, even at unity gain.
Operating from ± 5V supplies, the CLC415 consumes only
50mW of power per channel, yet maintains a 160MHz
small-signal bandwidth and a 1500V/µs slew rate. High density applications requiring an integrated solution will enjoy
the CLC415’s 70dB channel isolation (input referred @
5MHz).
With its exceptional differential gain and phase, typically
0.03% and 0.03˚ @ 3.58MHz, the CLC415 is designed to
meet the performance and cost per channel requirements of
high volume composite video applications. The CLC415’s
large-signal bandwidth, high slew rate and high drive capability are features well suited for RGB-video applications.
The CLC415 is a quad version of the high speed CLC406
while the CLC414 is a lower power quad version of the
same. Both of these quads afford the designer lower power
consumption and lower cost per channel with the additional
benefit of requiring less board space per amplifier.
Constructed using an advanced, complementary bipolar process and National’s proven current feedback architectures.
The CLC415 is available in several versions to meet a
variety of requirements.

Application Division
Feedback Resistor
Non-Inverting Source Impedance
The CLC415 achieves its exceptional AC performance while
requiring very low quiescent power by using the current
feedback topology and an internal slew rate enhancement
circuit. The loop gain and frequency response for a current
feedback op amp is predominantly set by the feedback
resistor value. The CLC415 is optimized for a gain of +6 to
use a 500Ω feedback resistor (use a 900Ω Rf for maximally
flat response at a gain of +2). Using lower values can lead
to excessive ringing in the pulse response while higher value
will limit the bandwidth.
Application Note OA-13 provides a more detailed discussion
of choosing a feedback resistor. The equations found in this
application note are to be considered a starting point for the
determination of Rf at any gain. The value of input impedance for the CLC415 is approximately 60Ω. These equations
do not account for parasitic capacitance at the inverting input
nor across Rf. The plot found below entitled “Recommended
Rf vs. Gain” offers values of Rf which will optimize the
frequency response of the CLC415 over its ± 1 to ± 10 gain
range. Unlike voltage feedback, current feedback op amps
require a non-zero Rf for unity gain followers.
For best operation, the DC source impedance looking out of
the non-inverting input should be less than 3kΩ but greater
than 20Ω. Parasitic self oscillations may occur in the input
transistors if the DC source impedance is out of this range.
This impedance also acts as the gain for the non-inverting
input bias and noise currents and therefore can become
troublesome for high values of DC source impedance. The
inverting configuration of Figure 3 shows a 25Ω resistor to
ground on the non-inverting input which insures stability but
does not provide bias current cancellation. The input bias
currents are unrelated for a current feedback amplifier which
eliminates the need for source impedance matching to
achieve bias current cancellation.
DS012751-17
FIGURE 3. Recommended Inverting Gain Circuit
DC Accuracy and Noise
Please refer to the application information section of the
CLC406 for a discussion of output offset voltage and spot
noise calculation.
Crosstalk
In any multi-channel integrated circuit there is an undesirable tendency for the signal in one channel to couple with
and reproduce itself in the output of another channel. This
effect is referred to as crosstalk. Crosstalk is expressed as
channel separation or channel isolation which indicates the
magnitude of this undesirable effect. This effect is measured
by driving one or more channels and observing the output of
the other undriven channel(s). The CLC415 plot page offers
two different graphs detailing the effect of crosstalk over
frequency. One plot entitled “All-Hostile Crosstalk Isolation”
graphs all-hostile, input referred crosstalk. All-hostile
crosstalk refers to the condition where three channels are
driven simultaneously while observing the output of the undriven fourth channel. Input-referred implies that crosstalk is
directly affected by gain and therefore a higher gain increases the crosstalk effect by a factor equal to that gain
setting.
The
plot
entitled
“Most
Susceptible
Channel-to-Channel Pulse Coupling” describes the effect of
crosstalk when one channel is driven with a 2VPP pulse while
the output of the most effected channel is observed.

ticular importance is the careful control of parasitic capacitances on the output pin. As the output impedance plot
shows, the closed loop output for the CLC415 eventually
becomes inductive as the loop gain rolls off with increasing
frequency. Direct capacitive loading on the output pin can
quickly lead to peaking in the frequency response, overshoot
in the pulse response, ringing or even sustained oscillations.
The “Settling Time vs. Capacitive Load” plot should be used
as a starting point for the selection of a series output resistor
when a capacitive load must be driven. A quad amplifier will
require careful attention to signal routing in order to minimize
the effects of crosstalk. Signal coupling through the power
supplies can be reduced with bypass capacitors placed
close to the device supply pins.
Evaluation Board
Evaluation PC boards (part number CLC730024 for
through-hole and 730031 for SOIC) for the CLC415 are
available.
(Continued)
Unused Amplifiers
It is recommended that any unused amplifiers in the quad
package be connected as unity gain followers (Rf =500Ω)
with the non-inverting input tied to ground through a 50Ω
resistor.
Slew Rate and Harmonic Distortion
Please see the application information for the CLC406.
Differential Gain and Phase
Differential gain and phase performance specifications are
common to composite video distribution applications. These
specifications refer to the change in small signal gain and
phase of the color subcarrier frequency (4.43MHz for PAL
composite video) as the amplifier output is swept over a
range of DC voltages. Application Note OA-08 provides an
additional discussion of differential gain and phase measurements.
Printed Circuit Layout
As with any high speed component, a careful attention to the
board layout is necessary for optimum performance. Of par-
