CIRRUS LOGIC PRODUCT DATA SHEET

CHARACTERISTICS/SPECIFICATIONS

ABSOLUTE MAXIMUM RATINGS

(PCIGND = CGND = CRYGND = 0 V, all voltages with respect to 0 V)

Notes: 1. Includes all power generated by AC and/or DC output loading.

2. The power supply pins are at recommended maximum values.

3. At ambient temperatures above 70° C, total power dissipation must be limited to less than 0.4 Watts.

WARNING: Operation beyond these limits may result in permanent damage to the device.

Normal operation is not guaranteed at these extremes.

RECOMMENDED OPERATING CONDITIONS

(PCIGND = CGND = CRYGND = 0 V, all voltages with respect to 0 V)
