Description

The TPA3129D2DAPR is Texas Instruments’ stereo Class-D audio power amplifier in a DAP package with an exposed pad for good heat dissipation. It provides two outputs to drive loudspeakers (typically 4 Ω or 8 Ω) from a single supply with high efficiency, making it suitable for battery-powered and compact electronics. Key features include protection mechanisms (undervoltage lockout, overcurrent, short-circuit/thermal shutdown), soft-start to minimize pops, and support for either filterless operation or with an external LC filter as needed. The device is designed for portable audio gear such as Bluetooth speakers, multimedia devices, and other small audio systems where efficiency and footprint are important. For exact electrical specs (output power, supply range, THD, quiescent current) and recommended layout, consult the official TI datasheet and application notes.

Features

Here are the main features of the TPA3129D2DAPR:
- Dual-channel, filterless Class-D audio amplifier (BTL outputs)
- No external output filter required; high efficiency
- Spread-spectrum switching to reduce EMI
- Soft-start/pop-free turn-on; standby/mute control
- Wide supply range and robust performance across loads
- Comprehensive protection: undervoltage/overvoltage, overcurrent/short to GND or supply, thermal shutdown with foldback
- Fault diagnostics/flag for fault conditions
- Differential inputs with selectable/fixed gain options
- EMI-optimized design suitable for compact applications
- RoHS-compliant, in DAPR package
Note: Exact output power, load ranges, and supply voltage specs depend on the specific operating conditions and should be verified in the datasheet for precise numbers.

Package

Package type: D2PAK (TO-263) power package.

Pinout

Pin count: 16 pins (DAPR package).
Function: Dual-channel, differential-input, Class-D audio power amplifier (BTL). Each channel drives a pair of outputs (OUTx+ and OUTx−). Differential inputs (INx+ and INx−). Power supply (VCC) and ground (GND). Control pins include SHDN (shutdown) and BYP (bypass/reference).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
- What kind of company: TI is an American multinational technology company that designs and manufactures semiconductors and integrated circuits (primarily analog and embedded processing ICs). It is one of the world's largest semiconductor producers.

Application

Application areas: 2-channel stereo audio power amplifier for consumer electronics needing high efficiency and small BOM. Typical uses include soundbars and home‑theater systems, TVs and set‑top boxes, mini hi‑fi systems, multimedia/PC speakers, gaming consoles, and other 8 Ω (or 4 Ω) loudspeaker applications using a filterless Class‑D design.

Equivalent

Closest TI equivalents: TPA3120D2, TPA3121D2, and TPA3123D2 (stereo, filter-free Class-D amps in the same family). There isn’t an exact 1:1 cross-brand equivalent. If substituting, match roughly 2.5 W per channel into 8 Ω, filter-free Class-D operation, similar supply range, and pinout/package.
