TPA3136D2PWP

Audio Amplifiers Overview

The TPA3136D2PWP is a Class-D stereo audio amplifier manufactured by Texas Instruments, housed in an HTSSOP-28 package. It delivers 10 W per channel into 8 Ω loads at 10% THD+N from a 13 V supply. The device operates within a wide supply voltage range of 4.5 V to 14.4 V and features a fixed gain of 26 dB. Total Harmonic Distortion plus Noise is specified at 0.05%. It supports single-ended or differential analog inputs and includes integrated SpeakerGuard protection.

Audio Amplifiers Feature Summary

• Advanced EMI suppression using spread spectrum control reduces system costs by allowing lower-cost output filters.
• SpeakerGuard protection circuitry incorporates power limiting and DC detection to safeguard connected speakers.
• Robust protection mechanisms include automatic recovery for pin-to-pin, pin-to-ground, and pin-to-power shorts.

Audio Amplifiers Applications

• Televisions
• Bluetooth and wireless speakers
• Mini speakers
• USB speakers
• Consumer audio equipment

Audio Amplifiers Procurement Notes

Verify the suffix 'PWPR' versus 'PWP' carefully, as packaging differs (Reel vs Tube). Confirm RoHS compliance status via the manufacturer's datasheet. Ensure the design accounts for humidity sensitivity during storage and handling. Validate that the 13V supply requirement aligns with the target application's power architecture before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when high efficiency without heat sinks is required for stereo applications. It is suitable for designs needing robust short-circuit protection and low distortion. Consider the 26 dB fixed gain for direct interface with standard audio sources. Evaluate the HTSSOP-28 thermal performance against the specific PCB layout constraints.

Audio Amplifiers Part Context

This part belongs to the TPA3136D2 series of efficient D-class audio amplifiers. It is designed to drive bridge-tied load (BTL) stereo speakers up to 10W. The series emphasizes cost-effective EMC compliance through spread spectrum technology. It serves as a solution for portable and stationary consumer audio devices requiring high power density.

Audio Amplifiers Replacement Considerations

The TPA3136AD2PWP is a related variant with a higher maximum operating temperature of +125°C but requires a minimum supply voltage of 8V. Verify if the wider voltage range of the TPA3136D2 is necessary for the specific power supply rails in the design.
