The platform switch and jumper settings shown in Table 2–1 are typical for the TPA152 EVM and will cause the TPA152 IC to mute when a plug is removed from platform headphone jack J10. Table 2–1. Typical TI Plug-N-Play Platform Jumper and Switch Settings for the TPA152... -
Page 13: Precautions
Precautions 2.1 Precautions Power Supply Input Polarity and Maximum Voltage Always ensure that the polarity and voltage of the external power connected to V power input connector J1, J2, and/or V power input connector J6 are correct. Overvoltage or reverse-polarity power applied to these terminals can open on-board soldered-in fuses and cause other damage to the platform, installed evaluation modules, and/or the power source. -
Page 14: Quick Start List For Platform
1) Ensure that all external power sources are set to OFF and that the platform power switch S1 is set to OFF. 2) Install a TPA152 module in platform socket U5, taking care to align the module pins correctly. 3) Use switch S2 to select or bypass the signal conditioning EVM (U1) 4) Set control signal Polarity jumper JP7 to Lo. -

The TPA152 Audio Power Amplifier Evaluation Module 3.2.1 TPA152 Audio Amplifier IC The TPA152 audio amplifier IC is a CMOS device intended primarily for high-performance line-level output and headphone driver applications. It is supplied in a very small surface-mount package and has been designed to operate from low supply voltages (between approximately 4.5 V and 5.5 V) -

3.2.3 Mute When the mute terminal of the TPA152 amplifier IC is taken high, the IC ceases operation. This is accomplished by applying a control signal to the module SD pin or by pressing the Shutdown switch, S1, on the module. When the control signal goes low or is removed (or the switch is released), amplifier operation resumes. -

Using The TPA152 EVM With the Plug-N-Play Evaluation Platform 3.3 Using The TPA152 EVM With the Plug-N-Play Evaluation Platform The TPA152 Audio Amplifier Evaluation Module was designed to be used with the TI Plug-N-Play Audio Amplifier Evaluation Platform. It simply plugs into socket U5. -
Page 22: Platform Signal Routing And Outputs
The audio signal from the input jacks can be applied to the signal conditioning socket (U1) if an EVM is installed there, or socket U1 can be bypassed and the audio input signal applied directly to the inputs of the TPA152 power amplifiers. Switch S2 selects or bypasses signal conditioning. -

Using The TPA152 EVM With the Plug-N-Play Evaluation Platform 3.3.3 Mute The TPA152 EVM is equipped with a mute control input pin. When this input is tied to V , the TPA152 amplifier IC on the module ceases operation. When the EVM control input is tied to GND or allowed to float, amplifier operation resumes. -

Using The TPA152 EVM Stand-Alone 3.4 Using The TPA152 EVM Stand-Alone Using the TPA152 Audio Power Amplifier Evaluation Module stand-alone is much the same as using it with the platform. The same 4.5-V to 5.5-V power supply requirement exists. Note that the mute signal applied to the EVM SD pin must be able to supply enough current to overcome the pulldown resistor on the module (20 kΩ). -
