(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions is not implied. Exposure to absolute-maximum conditions for extended periods may affect device reliability.

(2)

5-V tolerant inputs are PDN, RST, SCLK, LRCLK, MCLK, SDIN, SDA, and SCL.

(3)

Maximum pin voltage should not exceed 6 V.

(4)

DC voltage + peak AC waveform measured at the pin should be below the allowed limit for all conditions.

(1)

For operation at PVDD levels greater than 18 V, the modulation limit must be set to 93.8% via the control port register 0x10.

(2)

Continuous operation above the recommended junction temperature may result in reduced reliability and/or lifetime of the device.

ELECTRICAL CHARACTERISTICS
