(1)

Stresses beyond those listed under absolute 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 operation conditions are

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

(2)

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

(3)

Maximum pin voltage should not exceed 6.0V

(4)

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

This data was taken using 1 oz trace and copper pad that is soldered directly to a JEDEC standard high-k PCB. The thermal pad must

be soldered to a thermal land on the printed-circuit board. See TI Technical Briefs SLMA002 for more information about using the

HTQFP thermal pad
