Note 2: Design limits are guaranteed (but not 100% production tested). These limits are not used to calculate outgoing quality levels. Note 3: When measuring video amplifier bandwidth or pulse rise and fall times, a double sided full ground plane printed circuit board without socket is recommend- ed. Note 4: Operating Ratings indicate conditions of which the device is functional, but does not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. http:/ /www.national.com 2

TL/H/10006–16 Note: The p.c.b. layout shown above is suitable for evaluating the performance of the LM1201. Although it is similar to the typical application circuit of Figure 3, there is no c.r.t. driver stage. Instead, a feedback resistor is connected between Pins 8 and 9 and the brightness control is connected to Pin 6. Again, for best results, a socket should not be used for the LM1201.
