Video Line Driver  
C2  
Figure 32 shows the OPA2652 used as a video line  
driver. Its outstanding differential gain and phase  
allow it to be used in studio equipment, while its low  
cost and SOT23-8 package option also support  
consumer applications.

Demonstration Fixtures  
Two printed circuit boards (PCBs) are available to  
assist in the initial evaluation of circuit performance  
using the OPA2652 in its two package options. Both  
of these are offered free of charge as unpopulated  
PCBs, delivered with a user's guide. The summary  
information for these fixtures is shown in Table 1.  
Pulse Delay Circuit  
Figure 33 shows the OPA2652 used in a pulse delay  
circuit. This circuit cascades the two op amps in the  
OPA2652, each forming a single pole, active allpass  
filter. The overall gain is +1, and the overall delay  
through the filter is:

Computer simulation of circuit performance using  
SPICE is often useful when analyzing the  
performance of analog circuits and systems. This  
method is particularly true for video and RF amplifier  
circuits where parasitic capacitance and inductance  
can have a major effect on circuit performance.  
Check the Texas Instruments web site (www.ti.com)  
for available SPICE products (note that not all parts  
have models). These models do a good job of  
predicting small-signal AC and transient performance  
under a wide variety of operating conditions. They do  
not do as well in predicting the harmonic distortion or  
dG/dφ characteristics. These models do not attempt  
to distinguish between the package types in  
small-signal AC performance.

RF and RG need to be equal to maintain a constant  
gain magnitude. The rise and fall times of the input  
pulses, tr(IN), should be slow enough to prevent  
pre-shoot artifacts in the response.

Simple Bandpass Filter  
Figure 34 shows the OPA2652 used as simple  
bandpass filter. The OPA2652 is well-suited for this  
type of circuit because it is very stable at a noise  
gain of +1.
