FEATURES
DESCRIPTION
The TPA31xxD2 series are stereo efficient, digital
Supports Multiple Output Configurations
amplifier power stage for driving speakers up to
2×50-W into a 4-
Ω BTL Load at 21 V
100W/2
Ω in mono. The high efficiency of the
(TPA3116D2)
TPA3130D2 allows it to do 2x15W without external
2×30-W into a 8-
Ω BTL Load at 24 V
heat sink on a single layer PCB. The TPA3118D2 can
even run 2x30W/8
Ω without heat sink on a dual layer
(TPA3118D2)
PCB. If even higher power is needed the TPA3116D2
2×15-W into a 8-
Ω BTL Load at 15 V
does 2x50W/4
Ω with a small heat-sink attached to its
(TPA3130D2)
top side PowerPad. All three devices share the same
Wide Voltage Range: 4.5 V – 26 V
footprint enabling a single PCB to be used across
different power levels.
Efficient Class-D Operation
>90% Power Efficiency Combined with Low
The
TPA31xxD2
advanced
oscillator/PLL
circuit
Idle Loss Greatly Reduces Heat Sink Size
employs a multiple switching frequency option to
avoid AM interferences; this is achieved together with
Advanced Modulation Schemes
an option of Master/Slave option, making it possible
Multiple Switching Frequencies
to synchronize multiple devices.
AM Avoidance
The TPA31xxD2 devices are fully protected against
Master/Slave Synchronization
faults
with
short-circuit
protection
and
thermal

protection as well as over-voltage, under-voltage and
DC protection. Faults are reported back to the
Feedback Power Stage Architecture with High
