Texas Instruments TPA3107D2EVM

Overview

TPA3107D2EVM from Texas Instruments is an evaluation module for the TPA3107D2 15-W/channel Class-D stereo audio power amplifier IC, featuring integrated LC output filters, banana-jack speaker outputs, RCA analog inputs, and configurable gain/jumpers for rapid prototyping of high-efficiency audio amplification stages in consumer and professional audio systems.

For engineers reviewing the TPA3107D2EVM datasheet, TPA3107D2EVM pinout, TPA3107D2EVM application, or TPA3107D2EVM equivalent, this module supports quick functional validation of the TPA3107D2 amplifier under real-world load conditions (6–8 Ω), supply voltage sweep (10–26 V), gain configuration (20–36 dB), and master/slave synchronization - all without custom PCB design.

Technical Context

The TPA3107D2EVM implements a complete reference design around the TPA3107D2PAP QFP-64 IC, including input coupling networks, bootstrap capacitors, LC low-pass filters (33 µH + 1 µF per channel), and thermal management via exposed PowerPad layout. It supports both single-ended and fully differential analog inputs via jumper-selectable configurations (J9/J10).

Control logic is TTL-compatible: SD (active-low shutdown), MUTE (active-high mute), FAULT reporting (open-drain), and SYNC output (for multi-device switching synchronization). Gain is set by two binary-select jumpers (J12/J13) yielding four discrete levels (20/26/32/36 dB), while MSTR/SLV (J14) configures master/slave operation for synchronized switching across multiple EVMs.

FAQ

What is the purpose of the TPA3107D2EVM?

The TPA3107D2EVM is a Texas Instruments evaluation module built around the TPA3107D2 Class-D stereo audio power amplifier IC. Its purpose is to provide engineers with a ready-to-use, fully assembled platform - including LC output filters, RCA inputs, banana-jack speaker outputs, and configurable jumpers - to validate amplifier performance, test thermal behavior, and prototype audio subsystems without designing custom hardware. The TPA3107D2EVM enables rapid functional verification of the TPA3107D2 under real-world operating conditions.

Does the TPA3107D2EVM include the TPA3107D2 IC?

Yes, the TPA3107D2EVM includes one TPA3107D2PAP IC in a 64-pin QFP package (10 mm × 10 mm), mounted on the board with proper thermal vias and PowerPad grounding as specified in the official TI datasheet (SLOS509). This IC is the core amplifier component enabling the module's 15-W/channel output capability, and it is pre-soldered and tested per TI's evaluation board specifications. The TPA3107D2EVM relies entirely on this IC for its audio amplification function.

How do I configure the gain on the TPA3107D2EVM?

Gain on the TPA3107D2EVM is configured using two 2-position jumpers: GAIN0 (J12) and GAIN1 (J13). Each jumper position sets a TTL-compatible input to either GND (jumper installed) or VREG (~4 V, jumper removed). The four combinations yield gains of 20 dB (both jumpers installed), 26 dB (J13 installed, J12 removed), 32 dB (J13 removed, J12 installed), or 36 dB (both removed), as defined in Table 1 of the SLOU190 User's Guide. The TPA3107D2EVM's gain settings are hardware-controlled and require no software or external programming.

Can multiple TPA3107D2EVM boards be synchronized?

Yes, multiple TPA3107D2EVM boards can be synchronized using the SYNC output (test point TP2) and the MSTR/SLV control (jumper J14). One board must be configured as master (J14 removed), while others are set as slaves (J14 installed). This synchronizes the internal switching frequencies of their respective TPA3107D2 ICs, reducing beat frequencies and EMI in multi-channel or multi-amplifier systems. The TPA3107D2EVM implements this feature directly via its onboard routing and jumper options - no additional components are needed to achieve synchronization.

What safety and compliance limitations apply to the TPA3107D2EVM?

The TPA3107D2EVM is intended solely for engineering development, demonstration, or evaluation - not for end-product use. It is not certified for FCC, CE, RoHS, WEEE, or UL compliance, and lacks the safety isolation, EMI filtering, and enclosure required for consumer deployment. TI explicitly states it is not fit for general consumer use, life-support applications, or automotive environments unless separately qualified. Users must observe electrostatic precautions, respect the 10–26 V supply range, avoid exceeding 6 Ω minimum load, and monitor component temperatures during operation. The TPA3107D2EVM carries these restrictions as stated in its official User's Guide (SLOU190).
