Features 1.1 Features The TI TPA6101A2 audio amplifier evaluation module and the TI plug-n-play audio amplifier evaluation platform include the following features: - - TPA6101A2 Stereo Audio Power Amplifier Evaluation Module J J J J J J J J - 1-2 Fixed-gain of 2 dB (inverting) Dual channel, single-ended operation 50-mW output power into 16 Ω at 3.3 V Very low distortion — THD+N is less than 0.08% at 1 kHz and less than 0.2% from 20 Hz to 20 kHz into 16-Ω loads, and less than 0.
Description 1.2 Description The TPA6101A2 audio power amplifier evaluation module is a complete, low-power stereo audio power amplifier for high-fidelity line-level output, headphone, and small speaker applications. It consists of the TI TPA6101A2 50-mW stereo audio power amplifier IC in a very small MSOP package, along with a small number of other parts mounted on a circuit board that is approximately one and a quarter inches square (see Figure 1–1). Figure 1–1.
1-4 Introduction
Chapter 2 Quick Start The steps in this chapter can be followed to prepare the TPA6101A2 audio amplifier EVM for use. Using the TPA6101A2 EVM with the TI plug-n-play audio amplifier evaluation platform is a quick and easy way to connect power, signal and control inputs, and signal outputs to the EVM using standard connectors.
Precautions 2.1 Precautions Power Supply Input Polarity and Maximum Voltage Always ensure that the polarity and voltage of the external power connected to VCC power input connector J1, J2, and/or VDD power input connector J6 are correct. Overvoltage or reverse-polarity power applied to these terminals can open onboard soldered-in fuses and cause other damage to the platform, installed evaluation modules, and/or the power source.
Quick Start List for Platform 2.2 Quick Start List for Platform Follow these steps when using the TPA6101A2 EVM with the TI plug-n-play audio amplifier evaluation platform (see the platform user’s guide, literature number SLOU011, for additional details). Numbered callouts for selected steps are shown in Figure 2–1. - Platform preparations 1) Ensure that all external power sources are set to OFF and that the platform power switch S1 is set to OFF.
Quick Start List for Stand-Alone 2.3 Quick Start List for Stand-Alone Follow these steps to use the TPA6101A2 EVM stand-alone or when connecting it into existing circuits or equipment. Connections to the TPA6101A2 module header pins can be made via individual sockets, wire-wrapping, or soldering to the pins, either on the top or the bottom of the module circuit board. Numbered callouts for selected steps are shown in Figure 2–2. Figure 2–2.
