1-4 Introduction.
2-1 Quick Start Quick Start The steps in this chapter can be followed to quickly prepare the TP A102 MSOP audio amplifier EVM for use. Using the TP A102 MSOP 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 2-2 Quick Start 2.1 Precautions Power Supply Input Polarity and Maximum V oltage Always ensure that the polarity and voltage of the external power connected to V CC power input connector J1, J2, and/or V DD power input connector J6 are correct.
Quick Start List for Platform 2-3 Quick Start 2.2 Quick Start List for Platform Follow these steps when using the TP A102 MSOP EVM with the TI Plug-N-Play audio amplifier evaluation platform (see the platform user ’ s guide, SLOU01 1, for additional details).
Quick Start List for Stand-Alone 2-4 Quick Start 2.3 Quick Start List for Stand-Alone Follow these steps to use the TP A102 MSOP EVM stand-alone or when connecting it into existing circuits or equipment.
3-1 Details Details This chapter provides details on the TP A102 IC, the evaluation module, the steps in the Quick-Start List, additional application information, and a parts list for the TP A102 MSOP evaluation module. T opic Page 3.1 Precautions 3 – 2 .
Precautions 3-2 Details 3.1 Precautions Power Supply Input Polarity and Maximum V oltage Always ensure that the polarity and voltage of the external power connected to V CC power input connector J1, J2, and/or V DD power input connector J6 are correct.
The TP A102 MSOP Audio Power Amplifier Evaluation Module 3-3 Details 3.2 The TP A102 MSOP Audio Power Amplifier Evaluation Module The TP A102 MSOP audio power amplifier evaluation module is powered by a TP A102 150-mW stereo audio amplifier IC.
The TP A102 MSOP Audio Power Amplifier Evaluation Module 3-4 Details 3.2.1 TP A102 Audio Amplifier IC The TP A102 audio amplifier IC is a CMOS device intended primarily for high-performance line-level output, headphone driver , and small speaker applications.
The TP A102 MSOP Audio Power Amplifier Evaluation Module 3-5 Details 3.2.2 Module Gain The TP A102 MSOP evaluation module has a set gain of 4 (inverting) for each channel. However , the gain can be adjusted to a maximum of approximately 10 (inverting) by changing the value of feedback resistors (R2 and R4, Figure 3 – 3).
Using the TP A102 MSOP EVM With the Plug-N-Play Evaluation Platform 3-6 Details 3.3 Using the TP A102 MSOP EVM W ith the Plug-N-Play Evaluation Platform The TP A102 MSOP audio amplifier evaluation module is designed for use with the TI plug-n-play audio amplifier evaluation platform.
Using the TP A102 MSOP EVM With the Plug-N-Play Evaluation Platform 3-7 Details 3.3.2 Signal Routing Signal flow on the platform is controlled by two signal routing switches, as shown in Figure 3 – 5.
Using the TP A102 MSOP EVM With the Plug-N-Play Evaluation Platform 3-8 Details 3.3.3 Shutdown The TP A102 MSOP EVM is equipped with a shutdown control input pin. When this input is tied to V DD , the TP A102 amplifier IC on the module ceases operation and enters an ultralow-power state.
Using the TP A102 MSOP EVM With the Plug-N-Play Evaluation Platform 3-9 Details 3.3.4 Power Requirements The TP A102 MSOP audio power amplifier evaluation module can operate from a V DD voltage between approximately 2.
Using the TP A102 MSOP EVM With the Plug-N-Play Evaluation Platform 3-10 Details 3.3.5 Inputs and Outputs The TI plug-n-play audio amplifier evaluation platform is equipped with several standard conectors for audio inputs and outputs.
Using the TP A102 MSOP EVM Stand-Alone 3-1 1 Details 3.4 Using the TP A102 MSOP EVM Stand-Alone Using the TP A102 MSOP audio power amplifier evaluation module stand-alone is much the same as using it with the platform. The same 2.5-V to 5.5-V power supply requirement exists.
