7 Specifications

7.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VCC Supply voltage AVCC, PVCC –0.3 V 30 V V
VI Interface pin voltage SD, GAIN0, GAIN1, PBTL, FAULT (2) –0.3 V VCC + 0.3 V V
< 10 V/ms
PLIMIT –0.3 GVDD + 0.3 V
RINN, RINP, LINN, LINP –0.3 6.3 V
Continuous total power dissipation See Thermal Information
RL Minimum Load Resistance BTL: PVCC > 15 V 4.8
BTL: PVCC ≤ 15 V 3.2
PBTL 3.2
TA Operating free-air temperature –40 85 °C
TJ Operating junction temperature range(3) –40 150 °C
Tstg Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The voltage slew rate of these pins must be restricted to no more than 10 V/ms. For higher slew rates, use a 100-kΩ resister in series with the pins.
(3) The TPA3110D2 incorporates an exposed thermal pad on the underside of the chip. This acts as a heatsink, and it must be connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in the device going into thermal protection shutdown. See TI Technical Briefs SLMA002 for more information about using the TSSOP thermal pad.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±500
(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.
