Texas Instruments TPA2000D1EVM

Overview

TPA2000D1EVM from Texas Instruments is an evaluation module for the TPA2000D1 mono 2-W filterless Class-D audio power amplifier IC, designed to operate without external output filtering. It supports 2.7 V–5.5 V supply voltage, delivers 2 W into 4 Ω at 5 V, features four selectable gain settings (6/12/17.5/23.5 dB), and integrates differential stereo input with internal depop circuitry for transient suppression.

For engineers reviewing the TPA2000D1EVM datasheet, TPA2000D1EVM pinout, TPA2000D1EVM application, or TPA2000D1EVM equivalent, this module enables rapid validation of audio subsystems in portable electronics, speaker reference designs, and low-EMI audio interfaces where filterless Class-D operation and quick platform integration are critical.

Technical Context

The TPA2000D1EVM implements TI's proprietary filterless modulation scheme to eliminate external LC output filters while maintaining THD+N < 1% at full scale. It interfaces directly with the TI Plug-N-Play Audio Amplifier Evaluation Platform via 8-pin single-in-line header pins, supporting automatic power, signal, and control routing.

Gain configuration is set via two onboard jumpers (GAIN0/GAIN1) mapping to discrete 6/12/17.5/23.5 dB values; shutdown control is provided through a dedicated logic-level SHUTDOWN pin. The module uses a 16-pin TSSOP-packaged TPA2000D1PW IC with integrated bypass, oscillator, and thermal protection circuits.

FAQ

What is the primary function of the TPA2000D1EVM?

The TPA2000D1EVM is an evaluation module for the TPA2000D1 mono 2-W filterless Class-D audio power amplifier IC. Its purpose is to enable rapid functional verification, performance characterization, and system integration testing of the TPA2000D1 amplifier in real-world audio applications without requiring custom PCB design or external filtering components.

Does the TPA2000D1EVM require an external output filter?

No, the TPA2000D1EVM does not require an external output filter. It implements TI's filterless Class-D architecture, which uses advanced modulation and output stage design to meet EMI compliance and audio quality targets directly into 4 Ω loads without LC filtering-reducing BOM cost and board space.

How is gain configured on the TPA2000D1EVM?

Gain on the TPA2000D1EVM is configured using two onboard jumpers labeled GAIN0 and GAIN1. Their ON/OFF states select one of four fixed gain values: 6 dB, 12 dB, 17.5 dB, or 23.5 dB, as defined in Table 2–4 of the SLOU083A user's guide. No soldering or external components are required.

Can the TPA2000D1EVM be used standalone or only with the TI Plug-N-Play platform?

The TPA2000D1EVM supports both configurations: it can plug directly into the TI Plug-N-Play Audio Amplifier Evaluation Platform for automatic power, signal, and control interconnect, or be used stand-alone by wiring to its 8-pin header (IN+, IN−, VDD, GND, OUT+, OUT−, SHUTDOWN, GAIN pins) for integration into existing circuits.

What is the physical size and package of the TPA2000D1EVM board?

The TPA2000D1EVM is a 2-layer PCB measuring approximately 1.25 inches × 1.25 inches (31.75 mm × 31.75 mm). It hosts the TPA2000D1PW IC in a 16-pin TSSOP (PWP) package and features a single-in-line 8-pin header for platform or direct connection, as shown in Figure 1–1 and Section 2.4.3 of the SLOU083A documentation.
