3 Description
The TPA313xD2 are efficientstereo digital amplifier
power stages for driving speakers with up to
2x42W/4Q peak powerTPA3131/32D2 operates
heatsink-free with cooling to PCB through the bottom
side PowerPADM with sustained output power from 2
x4W/8Ω(TPA3131D2)to 2x25 W/8Q
(TPA3132D2).
The TPA313xD2 advanced oscillator/PLL circuit
employs a multiple switching frequencyoption to
avoid AM interferences; this is achieved together with
an option of Master and Slave synchronization
making it possible to synchronize multiple devices.
The TPA313xD2 are fully protected against faults with
short-circuit protection and thermal protection as well
as overvoltage, undervoltage, and DCprotection.
Faults are reported back to the processor to prevent
devices from being damagedduringoverload
conditions.
