[2] For frequency signals greater than 100 Hz, an additional 0.1% per 100 Hz is added. The accuracy of the duty cycle should be
calculated as:
Calculation example: Frequency setting = 4800 Hz, Duty cycle setting = 50%
The duty cycle accuracy (for frequency setting 4800 Hz) is calculated as 50% ± 5.1%.
[3] Characteristic applies when the positive or negative pulse width is greater than 50 μs.
[4] For frequency signals greater than 100 Hz, an additional 0.1% per 100 Hz is added. The accuracy of the pulse width should
be calculated as:
Calculation example: Frequency setting = 4800 Hz, Duty cycle setting = 50%
The pulse width accuracy (for frequency setting 4800 Hz and duty cycle setting 50%) is calculated as 0.1042 ms ±10.625 μs.

NOTE
• The rise and fall time are 25 μs typically between 10% and 90% of the
signal amplitude.
• The additional load regulation is 0.15 V/A.
