(1)
To minimize battery-current leakage, the SPLVDD and SPRVDD voltage levels should not be below the AVDD voltage level.
(2)
All grounds on board are tied together, so they should 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.
(3)
The maximum input frequency should be 50 MHz for any digital pin used as a general-purpose clock.

Electrical Characteristics
At 25°C, AVDD = HPVDD = IOVDD = 3.3 V, SPLVDD, SPRVDD = 3.6 V, DVDD = 1.8 V, fS (audio) = 48 kHz, CODEC_CLKIN
= 256 × fS, PLL = Off, VOL/MICDET pin disabled (unless otherwise noted)
