Accuracy
Input amplitude ranges according to above.
0.1 Hz – 10 kHz
40-60%
Exceeding above duty-cycle limits may cause inaccurate readings.
72 MHz
(± 100 ppm)
± 0.50 % (typ) up to 15 kHz
Input jitter (pulse time variations) will affect accuracy, especially at high frequencies.
Input impedance with pull-
up enabled
4.7 kΩ (± 2 %) to main supply voltage and 14.04kΩ (± 2 %) to ground.
Input impedance with pull-
up disabled
14.04kΩ (± 2 %) to ground.
