3. CHARACTERISTICS & SPECIFICATIONS

RECOMMENDED OPERATING CONDITIONS

ANALOG CHARACTERISTICS

• Min / Max characteristics and specifications are guaranteed over all operating ponditions.

• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.

• VA+ = 5 V ±5% VD+ = 3.3 V ±5% or 5 V ±5%; AGND = DGND = 0 V. All voltages with respect to 0 V.

• MCLK = 4.096 MHz

Notes: 1. Applies when the HPF option is enabled

2. Applies before system calibration. Specified as a percentage of full scale (FS).
