3. CHARACTERISTICS & SPECIFICATIONS
RECOMMENDED OPERATING CONDITIONS
ANALOG CHARACTERISTICS
•
Min / Max characteristics and specifications are guaranteed over all
Recommended Operating Conditions
•
Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
•
VA+ = VD+ = 5 V ±5%; AGND = DGND = 0 V; VREFIN = +2.5 V. All voltages with respect to 0 V.
•
MCLK = 4.096 MHz.
Notes: 1. Applies when the HPF option is enabled.
2. Applies when the line frequency is equal to the product of the Output Word Rate (OWR) and the value
of epsilon (
).
