n 3.4mA ICC provides 100MHz bandwidth and 14ns
settling (0.05%)
sumption, and flexibility of application. The supply current is
programmable over a 10 to 1 continuous range with a single
resistor, Rp. This feature enables the amplifier to be used in
a wide variety of high performance applications. Typical
performance at any supply current is exceptional:
n Fast disable capability
n 0.04% differential gain at ICC = 3.4mA
n 0.06% differential phase at ICC = 3.4mA

FIGURE 2. Recommended Inverting Gain Circuit
Description
The CLC505 is
current-feedback operational amplifier. Supply current and
consequently dynamic performance can be easily adjusted
by selecting the value of a single external resistor (Rp).
DS012755-31
a
programmable-supply current,
FIGURE 1. Recommended Non-Inverting Gain Circuit

Rp is connected from pin 8 to −VCC and VCC=+/−3V. Now
calculate Rp under new conditions:
Application Information (Continued)
Selecting an Operating Point
Rp=[(+VCC−1.6V)−(−VCC)]/Ip
Rp=[(+3V−1.6V)−(−3V)]/26µA
Rp=169kΩ
The operating point is determined by the supply current,
which in turn is determined by current (Ip) flowing out of pin
8. As the supply current is reduced the following effects will
be observed:
The CLC505 will have performance similar to Rp = 300kΩ
shown on the datasheet, but with 40% less power dissipation
due to the reduced supply voltages. (The op amp will also
have a more restricted common-mode range and output
swing.) This calculation is approximate and a prudent design
would include substantial performance margin for max/min
limits.

The CLC505 may be powered on and off very quickly by

±
5V supplies, the gate can be used to turn the amplifier on
and off. This is shown in Figure 3 below:
Both the specification pages and the plot pages illustrate
these effects to help make the supply current vs. perfor-
mance tradeoff. Performance is specified and tested at ICC
=1mA, 3.4mA, and 9mA as indicated in the datasheet. (Note
some test conditions and especially the load resistance are
different for the three supply current settlings.) The perfor-
mance plots show typical performance for all three supply
currents levels.
DS012755-49
When making the supply current vs. performance tradeoff, it
is first a good idea to see if one of the standard operating
points (ICC = 9mA, 3.4mA, or 1mA) fits the application. If it
does, performance guaranteed on the specification pages
will apply directly to your application. In addition, the value of
Rp may be obtained directly from the specification page.
FIGURE 3. Dynamic Control of Power Consumption
When the gate output is switched from high to low, the
CLC505 will turn on. In the off state, the supply current
typically reduces to 0.2mA or less. The speed with which the
CLC505 turns on or off is limited by the capacitance at pin 8.
To improve switching time, a speed up capacitor from the
gate output to pin 8 is recommended. The value of this
capacitor will depend on the total capacitance connected to
pin 8 and is best established experimentally. Turn-on and
turn-off times of 100ns to 200ns are achievable with ordinary
CMOS gates.
The following discussion will assist in selecting ICC for
applications that cannot operate at one of the specified
supply current settlings.
Use the typical performance plots for critical specifications to
select the best ICC. Now interpolate between the values of
ICC in the plots & specification tables to estimate the
max/min values in the application.
Example:
From the selected value of ICC the “programming current”
(Ip) may be easily calculated:
An open collector logic device is used to dynamically control
the power dissipation of the circuit. Here, the desired con-
nection for Rp is from pin 8 to the open collector logic device.
IP=ICC/39
The plot of ICC vs Ip in the plot pages shows this relationship
graphically. Knowing Ip leads to a direct calculation of Rp.
Rp= [(+VPP−1.6)−Vn]/ Ip
Rp=8.4/Ip (for +VCC=+5V and Vn =−5V)
Vn is the voltage externally applied to Rp. (Throughout the
data sheet and in most applications, Vn and −VCC are −5V.)
The term (+VCC−1.6V) is the voltage at pin 8.
DS012755-50
Now standard VCC, VEE and Rp does not have to be con-
nected to −VCC. In applications where non-standard supply
voltages are used or when there is a need to power down the
op amp via digital logic control. The value of Rp is adjusted
accordingly.
FIGURE 4. Controlling Power on State with TTL Logic
When the logic gate goes low, the CLC505 is turned on.
Performance desired is that given for ICC = 3.4mA under
standard conditions. From the ICC vs. Ip plot, Ip = 84µA. Then
calculating Rp:
First, an operating point needs to be determined from the
plots & specifications as discussed above. From this, Ip is
obtained. Ip, in concert with the available Vn determines Rp.
Rp=[(+VCC−1.6V)−(V n)]/Ip
Rp=[(+5V−1.6V)−(0)]84µA
Rp=40kΩ
Example
±
3V and performance in
An application requires that VCC
=
the 1mA operating point range. The required Ip can therefore
be determined as follows:
Ip=26µA
13
www.national.com
At ICC = 1mA and ICC = 3.4mA, the CLC505 is less capable
of driving a 150Ω load due to output current limitations. For
this reason lighter loads are used and the termination resis-
tor is omitted. The gain and load resistance for ICC = 3.4mA
are AV = +6 and RL = 500Ω and for ICC = 1mA; AV = +6 and
RL = 1kΩ.
Application Information (Continued)
Slew Rate
The rapid turn on and off ability of the CLC505 is not recom-
mended for signal isolation applications (such as multiplex-
ing). While the power dissipation of the amplifier drops in the
off state, the amplifier may still have some gain at low
frequencies. Causing feed through in multiplex application.
Source Impedance
For best results, source impedance in the non-inverting cir-
cuit configuration (see Figure 1) should be kept below 5kΩ.
Above 5kΩ it is possible for oscillation to occur, depending
on other circuit board parasitics. For high signal source
impedances, a resistor with a value of less than 5kΩ may be
used to terminate the non-inverting input to ground.
The performance desired is that given for ICC = 3.4mA under
standard conditions. From the ICC vs. Ip plot, Ip=84µA. Is
obtained now calculating Rp:
Slew rate limiting is a nonlinear response which occurs in
amplifiers when the output voltage swing cannot change as
rapidly as the applied input signal. The CLC505 has been
designed to avoid slew rate limiting in most circuit configu-
Feedback Resistor
In current-feedback op amps, the value of the feedback
resistor plays a major role in determining amplifier dynamics.
It is important to select the correct value. The CLC505
provides optimum performance with a 1kΩ feedback resistor.
Selection of an incorrect value can lead to severe rolloff in
frequency response, (if the resistor value is too large) or
peaking or oscillation, (if the value is too low.)
rations. The large signal (5VPP) bandwidth of 80MHz at ICC
=
3.4mA, is only slightly less than the 100MHz small signal
bandwidth. The result is a low distortion, linear system for
both small and large signals over the required system fre-
quency range.
The CLC505 reaches slew rate limits only for small
non-inverting gains. In other words, slew rate limiting is
constrained by common mode voltage swings at the input.
The large signal frequency response plot at a gain of +2 was
a break in the response, which indicates that a slew rate limit
has been reached. Note also that the frequency response
plots at a gain of +21 for large and small signal responses
are nearly identical.
Printed Circuit Layout
As with any high frequency device, a good PCB layout will
enhance performance. Ground plane construction and good
power supply bypassing close to the package are critical to
achieving full performance. In the non-inverting configura-
tion, the amplifier is sensitive to stray capacitance to ground
at the inverting input. Hence, the inverting node connections
should be small with minimal coupling to the ground plane.
Shunt capacitance across the feedback resistor should not
be used to compensate for this effect.
Differential Gain and Phase
Differential gain and phase are measurements useful prima-
rily in composite video channels. They are measured by
monitoring the gain and phase changes of a high frequency
carrier (3.58MHz typically) as the output of the amplifier is
swept over a range of DC voltages.
Precision buffed resistors (PRP8351 series from Precision
Resistive Products) with low parasitic reactances were used
to develop the data sheet specifications. Precision carbon
composition resistors will also yield excellent results. Stan-
dard spirally-trimmed RN55D metal film resistors will work
with a slight decrease in bandwidth due to their reactive
nature at high frequencies.
Specifications for the CLC505 include differential gain and
phase. Test signals based on a 1VPP video level. Test con-
ditions used are the following:
DC sweep range: 0 to 100 IRE units (black to white)
Carrier: 3.58MHz at 40 IRE units peak to peak
Evaluation PC boards (part number 730013 for through-hole
and 730027 for SOIC) for the CLC505 are available.
The amplifier conditions are significantly different for the
three values of supply current specified. At ICC = 9mA, the
amplifier is specified for a gain of +2 and 150Ω load (for a
backmatched 75Ω system). IRE amplitudes at ICC = 9mA,
are referred to the 75Ω load resistor.
