3 Description
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.
