TPA3113D2PWP

Overview

The TPA3113D2PWP is a 6-W filter-free stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 5.5 V to 18 V and supports load impedances of 4 Ω or 8 Ω. The device delivers high efficiency with low quiescent current, featuring a fixed gain of 30 dB. It includes integrated SpeakerGuard protection against thermal overload and short circuits. The component is housed in a 28-pin HTSSOP package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated SpeakerGuard technology provides automatic protection against thermal overload and output short circuits.
• Filter-free design eliminates the need for external LC filters, reducing bill of materials and board space.
• Fixed 30 dB gain configuration simplifies system integration and signal chain design.

Applications

• Portable Bluetooth speakers
• Desktop multimedia systems
• Active loudspeakers

Procurement Notes

Verify the specific suffix 'PWP' corresponds to the HTSSOP-28 tube packaging when sourcing. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure ESD handling protocols are followed during assembly due to humidity sensitivity classification.

Selection Notes

Select this component for applications requiring moderate stereo power output without complex filtering requirements. Compare against higher-power variants like the TPA3116D2 if increased wattage is necessary. Consider the fixed gain limitation when designing input stages for varying source levels.

Part Context

This part belongs to the TPA31xxD2 family of Class-D amplifiers from Texas Instruments.
