TPA311xD2-Q1 100-W and 50-W Class-D Stereo Automotive Amplifiers
1 Features 2 Applications
1
• Supports Multiple Output Configurations
• Automotive Audio
• Emergency Call
– 2 × 50 W Into a 4-Ω BTL Load at 21 V
(TPA3116D2-Q1)
• Driver Notifications
– 2 × 30 W Into an 8-Ω BTL Load at 24 V
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 Ω
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.
• Integrated Self-Protection Circuits Including
Overvoltage, Undervoltage, Overtemperature, DC-
