400, 480, 600, 800, 1200, 1600, 2400,
4800 Hz
[2][4] [3]
Duty cycle 0.39% to 99.60% ± 0.398% of full scale
[2][4]
Pulse width 1/Frequency 0.2 ms + (range/256)
Amplitude Fixed: 0 to + 2.8 V ± 0.2 V
Notes for square wave output specifications:
1 Output impedance: 3.5 kΩ maximum.
2 The positive or negative pulse width must be greater than 50 μs for adjusting the duty cycle or pulse width under different
frequencies. Otherwise, the accuracy and range will differ from the definition.
3 For signal frequency greater than 1 kHz, an additional 0.1% per kHz is added to the accuracy.
4 The accuracy for duty cycle and pulse width is based on a 5 V square wave input without dividing signal.
