Notes: [1] Typical values: VCC = 4.5 V, FS = 8 kHz and @ TA = 25°C, unless otherwise stated.
[2] Characterization data shows that sampling frequency resolution is ±5 percent across temperature and voltage
ranges.
[3] Characterization data shows that duration resolution is ±5 percent across temperature and voltage ranges.
[4] Vcc=2.4 V~5.5V
