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.
NOTES: 1. VREF is a 1.8-V supply derived from regulators internal to the TAS5028A 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.
2. 5-V tolerant inputs are RESET, PDN, MUTE, HP_SEL, SCLK, LRCLK, MCLK, SDIN1, SDIN2, SDIN3, SDIN4, SDA, and SCL.
