TPA3116D2DADR SMD IC Audio amplifier HTSSOP-32 TPA3116D2DADR

Product Overview:

A family of high-efficiency, filter-free Class-D stereo power amplifier integrated circuits designed to drive speakers in dual-channel bridge-tied load (BTL) or single-channel parallel bridge-tied load (PBTL) configurations. Combining a feedback power-stage architecture with high power supply rejection ratio (PSRR), it reduces overall power supply requirements while delivering high-quality audio amplification with minimal external component counts.

Core Specifications:

Manufacturer: Texas Instruments

Package Type: 32-pin HTSSOP (Thin Shrink Small Outline Package with Thermal Pad)

Function: Filter-Free Class-D Stereo Audio Amplifier Family with AM Avoidance

Input Channels: 2 Independent Analog Input Channels supporting single-ended or fully differential input topologies

Control Interface: Multi-Pin Analog and Logic Control Interface including Master/Slave synchronization pins (SYNC), Programmable Gain Settings (GAIN0, GAIN1), Shutdown Control (SD-bar), Fault Reporting (FAULT-bar), and Mute Control (MUTE)

Features

• Scalable Power Output Levels: The family supports multiple power options, delivering up to 2 x 50W into a 4-Ohm BTL load (TPA3116D2), 2 x 30W into an 8-Ohm BTL load (TPA3118D2), or 2 x 15W into an 8-Ohm BTL load (TPA3130D2).

• Flexible Operating Supply: Features a wide positive power supply operating range spanning from 4.5V up to 26V.

• High Conversion Efficiency: Exceeds 90 percent power efficiency paired with low internal idle losses, significantly reducing board heat and minimizing external heatsink size requirements.

• Advanced Switching Options: Supports multiple programmable switching frequencies up to 1.2 MHz, and integrates clock synchronization functionality to facilitate multi-device configurations.

• Integrated AM Avoidance: Employs specialized high-frequency modulation schemes to actively eliminate interference on nearby AM radio reception bands.

• Programmable Power Limiting: Incorporates a dedicated PLIMIT pin that allows engineers to adjust a threshold voltage to protect connected speakers from over-power damage.

• Complete Self-Protection Suite: Features hard-wired fault circuitry protecting the chip against overvoltage, undervoltage, overtemperature, direct-current speaker detection, short-circuits, and thermal runaway.

Applications

• Television Soundbars and Smart TVs: Drives high-power audio outputs within slim flatscreen profiles.

• Portable Wireless Speakers: Provides highly efficient audio processing to extend battery operating lifetimes in portable docks and boomboxes.

• Home Audio Systems and Receivers: Powers multi-channel active bookshelf monitors, stereo receivers, and surround sound components.

• Public Address and Commercial Audio: Acts as the localized amplifier block inside distributed public announcements and commercial audio distribution gear.
