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.

5-V tolerant inputs are RESET, PDN, MUTE, HP_SEL, SCLK, LRCLK, MCLK, SDIN1, SDIN2, SDIN3, SDIN4, SDA, and SCL.

(4)
VREF is a 1.8-V supply derived from regulators internal to the TAS5518C chip. VREF is on terminals VRA_PLL, VRD_PLL, VR_DPLL,
VR_DIG, and VR_PWM. These terminals are provided to permit use of external filter capacitors, but should not be used to source power
to external devices.
