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 TA = 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.
