TPA3116D2-Q1

The TPA3116D2-Q1 is a high-efficiency Class D audio amplifier designed for automotive and industrial applications, manufactured by Texas Instruments. It delivers up to 100W of continuous power into a 4Ω load with exceptional thermal stability and low distortion, making it ideal for demanding audio environments where performance and reliability are critical. This device features a wide supply voltage range from 8V to 28V, enabling compatibility with various vehicle electrical systems, including 12V and 24V platforms. Its integrated protection circuitry includes over-temperature shutdown, under-voltage lockout, short-circuit protection, and thermal shutdown, ensuring robust operation even under adverse conditions. The amplifier also supports both stereo and bridged-mode configurations, offering flexible design options for different speaker setups. The TPA3116D2-Q1 incorporates advanced digital signal processing capabilities, such as programmable gain control and dynamic range compression, allowing precise tuning of audio output levels and clarity. It includes an I²C-compatible serial interface for real-time configuration and monitoring, simplifying integration into modern embedded systems. Additionally, the chip operates with a high switching frequency (typically 500kHz), which reduces external filter requirements and improves electromagnetic compatibility (EMC). Designed to meet AEC-Q100 Grade 1 qualification standards, this amplifier is built for harsh automotive environments, including extreme temperature variations, vibration, and EMI exposure. Its compact 32-pin QFN package enables efficient board layout and thermal management in space-constrained applications. Common applications include premium car audio systems, active noise cancellation modules, and industrial sound reinforcement solutions. Whether used in infotainment systems or ruggedized public address equipment, the TPA3116D2-Q1 ensures clear, powerful sound reproduction while maintaining low power consumption and high efficiency—key factors for extending battery life and reducing heat generation in portable or mobile systems.
