Notes:
[1] _{Conditions are VCC = 5.5V, TA = 25°C and sampling frequency (FS) at 8kHz, unless specified.}
[2] _{Not all specifications are 100 percent tested. All Min/Max limits are guaranteed by Nuvoton via design, electrical}
testing and/or characterization.
[3] _{When different FS is applied, the value will change accordingly. Also, stability of internal oscillator may vary as much}
as +10% over the operating temperature and voltage ranges.
[4] _{k = 1000.}
