(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-rated conditions for extended periods may affect device reliability.

Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) All grounds on board are tied together, so they must not differ in voltage by more than 0.2-V maximum for any combination of ground signals. By use of a wide trace or ground plane, ensure a low-impedance connection between HPVSS and DVSS.
(2) To minimize battery-current leakage, the SPKVDD voltage level must not be below the AVDD voltage level.
(3) The maximum input frequency must be 50 MHz for any digital pin used as a general-purpose clock.

(1) Ratio of output level with 1-kHz full-scale sine-wave input, to the output level with the inputs short-circuited, measured A-weighted over a 20-Hz to 20-kHz bandwidth using an audio analyzer.
(2) All performance measurements done with 20-kHz low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may result in higher THD+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter removes out-of-band noise, which, although not audible, may affect dynamic specification values.
(3) DAC to speaker-out PSRR is a differential measurement calculated as PSRR = 20 × log(ΔVSPK(P + M) / ΔVSPKVDD).
(4) DAC to headphone-out PSRR measurement is calculated as PSRR = 20 × log(ΔVHPOUT / ΔVHPVDD).
