DESCRIPTION
The TPA31xxD2 series are stereo efficient, digital
amplifier power stage for driving speakers up to
100W/2Ω in mono. The high efficiency of the
TPA3130D2 allows it to do 2x15W without external
heat sink on a single layer PCB. The TPA3118D2 can
even run 2x30W/8Ω without heat sink on a dual layer
PCB. If even higher power is needed the TPA3116D2
does 2x50W/4Ω with a small heat-sink attached to its
top side PowerPad. All three devices share the same
footprint enabling a single PCB to be used across
different power levels.
The TPA31xxD2 advanced oscillator/PLL circuit
employs a multiple switching frequency option to
avoid AM interferences; this is achieved together with
an option of Master/Slave option, making it possible
to synchronize multiple devices.
The TPA31xxD2 devices are fully protected against
faults with short-circuit protection and thermal
protection as well as over-voltage, under-voltage and
DC protection. Faults are reported back to the
processor to prevent devices from being damaged
during overload conditions.
