Hello，
Our customer used AM26C32 for Servo driver application, and his application is singed-ended input, INCENC_V- connected VCC_+5V,INCENC_V+ connected signal source, but he found that the duty cycle is changed when the frequency is higher than 200Khz. So could you please help to analysis?
Below is the tested results and schematic:
The three testes conditions are as this:
1)R248=R228=10K, R234=R232=3.3K, and the high level appears 504ns.(input is 1Mhz, 50% duty cycle).
2)R248=R228=10K, R234=R232=6.2K,and the high level appears 720ns(input is 1Mhz, 50% duty cycle).
3)R248=R228=10K, R234=R232= 2K,and the high level appears 460ns(input is 1Mhz, 50% duty cycle).
Best regards
Kailyn
