Texas Instruments TPA2017D2RTJEVM

Overview

TPA2017D2RTJEVM from Texas Instruments is a fully assembled, stand-alone evaluation module for the TPA2017D2RTJ stereo filter-free Class-D audio power amplifier with integrated AGC and DRC functions. It operates from 4.5 V to 5.5 V, delivers up to 2 W per channel into 4 Ω at 1% THD+N, and supports configurable gain modes via jumper-selectable AGC1/AGC2 inputs - designed for rapid prototyping of portable audio systems.

For engineers reviewing the TPA2017D2RTJEVM datasheet, TPA2017D2RTJEVM pinout, TPA2017D2RTJEVM application, or TPA2017D2RTJEVM equivalent, this EVM enables immediate functional validation of speaker drive capability, AGC/DRC behavior under real-world signal dynamics, and layout considerations for QFN20-RTJ-based Class-D amplifier designs.

Technical Context

The TPA2017D2RTJEVM implements the full signal path of the TPA2017D2RTJ IC: differential or single-ended RCA inputs feed into the amplifier's analog front-end; AGC1/AGC2 jumpers configure limiter-only, full AGC+DRC+noise gate, or bypass modes; and dual 2-W Class-D outputs drive speakers via binding posts with integrated EMI filtering (L1–L4) and decoupling (C1–C23).

It integrates all required passive components - including 10 µF input bulk capacitance (C1), 1 µF local VDD decoupling (C6–C9, C13, C15), 0.1 µF high-frequency bypass (C10–C12, C14), and 1000 pF output filtering (C16–C19) - optimized for stable operation across 4.5–5.5 V supply and minimal PCB footprint using 0603/0805/1206 packages.

FAQ

What is the primary function of the TPA2017D2RTJEVM?

The TPA2017D2RTJEVM is a dedicated evaluation module for the TPA2017D2RTJ stereo Class-D audio amplifier IC. It provides a complete, ready-to-use platform - including input jacks, output binding posts, AGC configuration jumpers, and full passive support network - to validate audio performance, AGC/DRC behavior, thermal response, and PCB layout practices before integrating the TPA2017D2RTJ into a custom design.

Does the TPA2017D2RTJEVM require an external microcontroller to operate?

No, the TPA2017D2RTJEVM operates autonomously without firmware or host control. AGC mode is set via physical jumpers (AGC1/AGC2), enable/disable is controlled by a momentary switch (EN), and audio input is accepted directly through RCA connectors. The TPA2017D2RTJEVM is designed for immediate plug-and-play testing using standard lab equipment.

What speaker load impedance is supported by the TPA2017D2RTJEVM?

The TPA2017D2RTJEVM supports 4 Ω to 8 Ω speakers per channel, as validated by the TPA2017D2RTJ IC's specifications and the EVM's output stage design. The binding post outputs (OUTL±, OUTR±) are rated for continuous 2 W into 4 Ω at 5 V supply, with thermal derating above that impedance per the TPA2017D2RTJ datasheet.

Can the TPA2017D2RTJEVM be powered from a USB port?

Yes - the TPA2017D2RTJEVM accepts 4.5 V to 5.5 V DC input via banana jacks (VDD/GND), making it compatible with regulated 5 V USB power supplies. However, peak current draw reaches 1 A, so a USB port must deliver ≥5 V at ≥1.2 A (including margin) to avoid brownout during high-output transients.

Is the TPA2017D2RTJEVM RoHS-compliant and lead-free?

Yes, the TPA2017D2RTJEVM is fully RoHS-compliant and Pb-free, as explicitly stated in the User's Guide. All components - including the TPA2017D2RTJ IC, capacitors, resistors, ferrite beads, and connectors - meet JEDEC J-STD-609A Class 1 marking requirements and TI's green packaging standards.
