3 Description
(TPA3118D2-Q1)
The TPA311xD2-Q1 devices are automotive stereo,
Wide Voltage Range: 4.5 V to 26 V
efficient, digital-amplifier power stages for driving
Efficient Class-D Operation
speakers up to 100 W into 2
Ω in mono. The
>90% Power Efficiency Combined With Low
TPA3118D2-Q1 can even drive 2 × 30 W into 8
Idle Loss Greatly Reduces Heat Sink Size
without a heat sink on a dual-layer PCB. If even
higher power is needed, the TPA3116D2-Q1 drives
Advanced Modulation Schemes
2 × 50 W into 4
Ω with a small heat sink attached to
Multiple Switching Frequencies
its top-side thermal pad.
AM Avoidance
The TPA311xD2-Q1 advanced oscillator and PLL
Master and Slave Synchronization
circuit employ a multiple-switching-frequency option
Up to 1.2-MHz Switching Frequency
to avoid AM interference; this is achieved together
with an option of either master or slave selection,
Feedback Power-Stage Architecture With High
making it possible to synchronize multiple devices.
PSRR Reduces PSU Requirements
Programmable Power Limit
The TPA311xD2-Q1 devices are fully protected
against faults with short-circuit protection and thermal
Differential and Single-Ended Inputs
protection as well as overvoltage, undervoltage and
Stereo BTL and Mono PBTL Modes
dc protection. Faults are reported back to the
Single Power Supply Reduces Component Count
processor to prevent devices from being damaged
during overload conditions.
