Test Conditions (unless otherwise stated, VCC1 = 5 V, VCC2/VCC3/DEF VCC = 9 V, Ta = 25 ± 3°C)
Switching Mode
SW15 SW49 SW50 SW53
Test Conditions
1) Repeat steps 1) to 3) of V15, then observe pin 5.
2) Input a pulse like that shown below to pin 27 and measure the response time TVML1 (2) at that input.
3) Similarly, input the pulse to pin 21 and measure the response time TVML3 (4) at that input.
4) Input the sine wave of frequency FVH to TP78, set the aperture compensator peak frequency to 7.7M (111), and
measure the response time TVMH1 (2) as in 2) above.
5) Similarly, input the pulse to pin 21 and measure the response time TVMH3 (4) at the input.
