# TPA3140D2PWP ## Description The Texas Instruments TPA3140D2 is a high-efficiency, Class-D audio power amplifier designed for driving bridged-tied stereo speakers with outputs up to 10 W per channel into 6 Ω or 8 Ω loads. With advanced EMI suppression technology, including spread spectrum control and a 1SPW modulation scheme, the TPA3140D2 ensures robust performance while minimizing electromagnetic interference. Operating within a wide supply voltage range from 4.5 V to 14.4 V, this amplifier eliminates the need for heat sinks due to its up to 90% efficient Class-D operation. Integrated SpeakerGuard™ protection features such as automatic gain limit (AGL), adjustable power limiter, and DC protection enhance speaker safety and audio quality. Additionally, the TPA3140D2 includes comprehensive protection against pin-to-pin, pin-to-ground, and pin-to-power short circuits, as well as thermal protection with auto recovery. The device offers four selectable fixed gain settings and supports both single-ended and differential analog inputs, making it suitable for a variety of consumer audio applications including televisions, wireless speakers, mini speakers, and USB speakers. The TPA3140D2 is available in a 28-pin HTSSOP package, ensuring ease of integration into compact designs. ## Project Details - **Owner:** bakers - **Created:** 9/9/2024 - **Last Updated:** 7/18/2025 - **Visibility:** Public - **Manufacturer Part Number:** TPA3140D2PWP - **License:** https://creativecommons.org/licenses/by/4.0/ - **Materials:** NIPDAU - **Operating Temperature:** -40 to 85Celsius - **Package or Case Code:** 28-HTSSOP - **Part Type:** TPA3140D2PWP - **Datasheet URL:** https://www.ti.com/lit/ds/symlink/tpa3140d2.pdf - **Compliance:** RoHS - **Manufacturer Name:** Texas Instruments - **Copies:** 1 *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/bakers/tpa3140d2pwp~r8](https://www.flux.ai/bakers/tpa3140d2pwp~r8).* --- *Generated from [https://www.flux.ai/bakers/tpa3140d2pwp~r8](https://www.flux.ai/bakers/tpa3140d2pwp~r8)*
