- LTC LT1007 MACROMODEL DEMO: OUTPUT = V(55)

- * Walt Jung
- * LT1007 transient response demo test circuit
- * original edit 12/14/89
- * updated 06/28/90
- *
- * This circuit is an example of one which is deceptively simple,
- * yet it readily demonstrates the performance of the LT1007 op
- * amp macromodel. This model uses phase/frequency extensions to
- * the basic Boyle type macromodel architecture.
- *
- * The test circuit is a simple voltage follower operating from
- * +/-15V power supplies, tested for transient response, for 5
- * microseconds. As such, this test reveals a lot of valuable
- * information on how the model converges, how fast it performs the
- * simulation, and finally, the relative comparison of the pulse
- * response with that of the data sheet (ref p 2-63, lower left, LTC
- * 1990 data book).
- *
- * In this demo, the Probe CMD file supplied calls up display parameters
- * which show the transient response over the 5 microsecond
- * interval. You can modify this command file by subsituting other
- * models, for relative performance comparisions. Further comments
- * are contained in LTC App Note # 41 (1 800 637-5545).
