DS630F1 5
2. CHARACTERISTICS/SPECIFICATIONS
• Min / Max characteristics and specifications are guaranteed over all Operating Conditions.
• Typical characteristics and specifications are measured at nominal supply voltages and T
A
= 25°C.
• DGND = 0 V. All voltages with respect to 0 V.
ANALOG CHARACTERISTICS
Notes: 1. Applies after system calibration
2. Effective Input Impedance (EII) is determined by clock frequency (DCLK) and Input Capacitance (IC).
EII = 1/(IC*DCLK/4). Note that DCLK = MCLK / K.
