Notes:
[1] Conditions are V
CC
= 5.5V, T
A
= 25 °C and sampling frequency (F
S
) at 8kHz, unless specified.
[2] Not all specifications are 100 percent tested. All Min/Max limits are guaranteed by Winbond via design,
electrical testing and/or characterization.
[3] When different F
S
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.
