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.
• DCLK = 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.
