TPA3118D2DAPR Description
IC AMP CLASS D STER 30W 32HTSSOP
The TPA31xxD2 series are stereo efficient, digital amplifier power
stage for driving speakers up to 100W / 2 Ω in mono. The high
efficiency of the TPA3130D2 allows it to do 2 × 15 W without
external heat sink on a single layer PCB. The TPA3118D2 can even
run 2 × 30 W / 8 Ω without heat sink on a dual layer PCB. If even
higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ω with a
small heatsink 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 either master or 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
overvoltage, undervoltage, and DC protection. Faults are reported
back to the processor to prevent devices from being damaged during
overload conditions.
