FEATURES DESCRIPTION
• Supports Multiple Output Configurations The TPA31xxD2 series are stereo efficient, digital
amplifier power stage for driving speakers up to
– 2×50-W into a 4-Ω BTL Load at 21 V 100W/2Ω 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
(TPA3118D2) even run 2x30W/8Ω without heat sink on a dual layer
– 2×15-W into a 8-Ω BTL Load at 15 V PCB. If even higher power is needed the TPA3116D2
(TPA3130D2) does 2x50W/4Ω with a small heat-sink attached to its
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
• Efficient Class-D Operation different power levels.
– >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
– Advanced Modulation Schemes avoid AM interferences; this is achieved together with
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
– Up to 1.2 MHz Switching Frequency protection as well as over-voltage, under-voltage and
• Feedback Power Stage Architecture with High DC protection. Faults are reported back to the
PSRR Reduces PSU Requirements processor to prevent devices from being damaged
during overload conditions.
• Programmable Power Limit
• Differential/Single-Ended Inputs Simplified Application Circuit
• Stereo and Mono Mode with Single Filter Mono
Configuration
