The TPA311xD2-Q1 devices are automotive stereo, efficient, digital-amplifier power stages
for driving speakers up to 100 W into 2 Ω in mono. The TPA3118D2-Q1 can even drive 2 × 30 W into 8
Ω without a heat sink on a dual-layer PCB. If even higher power is needed, the TPA3116D2-Q1 drives
2 × 50 W into 4 Ω with a small heat sink attached to its top-side thermal pad.
The TPA311xD2-Q1 advanced oscillator and PLL circuit employ a
multiple-switching-frequency option to avoid AM interference; this is achieved together with an
option of either master or slave selection, making it possible to synchronize multiple devices.
The TPA311xD2-Q1 devices are fully protected against faults with short-circuit protection
and thermal protection as well as overvoltage, undervoltage and dc protection. Faults are reported
back to the processor to prevent devices from being damaged during overload conditions.
