Application Discussion  
Introduction  
Typical Performance plots are valid for both devices  
under the specified conditions. Generally, lowering Rf  
from its recommended value will peak the frequency  
response and extend the bandwidth while increasing its  
value will roll off the response. Reducing the value of Rf  
toofarbelowitsrecommendedvaluewillcauseovershoot,  
ringing and eventually oscillation. For more information  
see Application Note OA-20 and OA-13.  
TheCLC431andtheCLC432aredualwidebandcurrent-  
feedback op amps that operate from single (+10V to  
+33V) or dual (±5V to ±16.5) power supplies. The  
CLC431 is equipped with a disable feature and is offered  
in 14-pin DIP and SOIC packages. The CLC432 is  
packaged in a standard 8-pin dual pinout and is offered  
inan8-pinDIPandSOIC.Evaluationboardsareavailable  
for each version of both devices. The evaluation boards  
canassistinthedeviceand/orapplicationevaluationand  
were used to generate the typical device performance  
plots on the preceding pages.  
In order to optimize the devices' frequency and phase  
response for gains other than +2V/V it is recommended  
to adjust the value of the feedback resistor. The two plots  
found in the Typical Performance section entitled  
"Recommended Rf vs. Gain" provide the means of  
selecting the feedback-resistor value that optimizes  
frequency and phase response over the CLC431/  
CLC432's gain range. Both plots show the value of Rf  
approaching a nonzero minimum at high non-inverting  
gains, which is characteristic of current-feedback op  
amps and yields best results. The linear portion of the  
twoRf vs. Inverting-gaincurvesresultsfromthelimitation  
placed on Rg (i.e. Rg 50) in order to maintain an  
adequateinputimpedancefortheinvertingconfiguration.  
It should be noted that for stable operation a non-  
inverting gain of +1 requires an Rf equal to 1kfor both  
the CLC431 and the CLC432.  
Each of the CLC431/CLC432's dual channels provide  
closely matched DC & AC electrical performance  
characteristics making them ideal choices for wideband  
signal processing. The CLC431, with its disable feature,  
can easily be configured as a 2:1 mux or several can be  
usedtoforma10:1muxwithoutperformancedegradation.  
Thetwoclosely-matchedchannelsoftheCLC432canbe  
combinedtoformcompositecircuitsforsuchapplications  
as filter blocks, integrators, transimpedance amplifiers  
and differential line drivers and receivers.  
Feedback Resistor Selection  
The loop gain and frequency response for a current-  
feedback operational amplifier is determined largely by  
the feedback resistor (Rf). Package parasitics also  
influence ac response. Since the package parasitics of  
the CLC431 and the CLC432 are different, the optimum  
frequencyandphaseresponsesareobtainedwithdifferent  
valuesoffeedbackresistor(forAV=+2;CLC431:Rf=866,  
CLC432: Rf=750). The Electrical Characteristics and  
CLC431 Disable Feature  
The CLC431 disable feature can be operated either  
single-endedlyordifferentiallytherebyaccommodatinga  
wide range of logic families. There are three pins asso-  
ciated with the disable feature of each of the CLC431's  
two amplifiers:
