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 (

ε).
