TPA3002D2PHP

Overview

The TPA3002D2PHP is a Class-D stereo audio amplifier from Texas Instruments, designed for high-efficiency sound reproduction in portable and desktop applications. It delivers 2x15W into a 4Ω load with low total harmonic distortion. The device integrates a fixed gain of 26dB and supports mono bridged (BTL) operation for higher power output. Key electrical parameters include a wide supply voltage range of 5V to 26V and an ultra-low quiescent current of 1.8mA. It features thermal shutdown and short-circuit protection, ensuring robust operation under varying load conditions while maintaining high signal-to-noise ratio performance.

Feature Summary

• High efficiency Class-D architecture minimizes heat dissipation and extends battery life in portable devices.
• Integrated fixed gain simplifies system design by reducing external component count.
• Built-in protection mechanisms including thermal shutdown and short-circuit protection enhance reliability.

Applications

• Portable Bluetooth speakers
• Desktop multimedia systems
• Active subwoofers

Procurement Notes

Verify the exact suffix PHP indicates the specific tape-and-reel packaging configuration when ordering. Confirm that the operating temperature range meets your environmental requirements. Ensure the PCB layout adheres strictly to the datasheet recommendations for thermal management and EMI suppression to maintain specified performance levels.

Selection Notes

Choose this model when a compact, high-power stereo solution is required without complex digital interfaces. It is suitable for designs prioritizing analog simplicity and cost-effectiveness over programmable gain or DSP integration. Evaluate the thermal constraints of the enclosure, as the device requires adequate copper area for heat sinking to sustain maximum power output.

Part Context

This component belongs to Texas Instruments' TPA300x series of Class-D amplifiers, which are engineered for consumer audio electronics. The series emphasizes high power density and ease of implementation. The TPA3002D2PHP specifically targets stereo applications where space and power efficiency are critical constraints compared to linear amplifier alternatives.

Replacement Considerations

Direct pin-compatible replacements within the same family may offer different power ratings or protection features. Verify that any substitute maintains the same supply voltage range and gain configuration to avoid redesigning the surrounding analog circuitry.
