Page 11: Introduction
The platform has room for a single TPA6030A4 evaluation module and is a convenient vehicle for demonstrating TI’s audio power amplifier and related evaluation modules. The EVM simply plugs into the platform, which... -
Page 12: Special Notes Regarding The Data Sheet
Special Notes Regarding the Data Sheet 1.4 Special Notes Regarding the Data Sheet The TPA6036A4EVM may have markings not consistent with the data sheet. Some EVMs have an incorrect supply voltage marked on them. The correct supply range is 7 V to 15 V, not 5 V to 15 V. The EVM and this user’s guide refer to the two input pins as HP and LINE, and refer to the control pin as HP/LINE. -

Page 15: 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 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. -
Page 16: 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 TPA6030A4 module in platform socket U2, taking care to align the module pins correctly. 3) Use switch S2 to select or bypass the signal conditioning EVM (U1). - Page 17 SE and BTL volumes; counterclockwise increases the difference. 15) Turning potentiometer R3 (SEMAX) clockwise increases the maximum SE volume; counterclockwise decreases the maximum SE volume.

Page 18: Quick Start List For Stand-Alone
2.3 Quick Start List for Stand-Alone Follow these steps to use the TPA6030A4EVM stand-alone or when connecting it to existing circuits or equipment. Connections to the TPA6030A4 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. - Page 19 10) SHUTDOWN: A low voltage applied to this pin shuts down the amplifier IC on the module; a high voltage or float on this pin allows normal operation. Refer to the TPA6030A4 data sheet for trip level information. Power-Up 11) Verify correct voltage and input polarity and set the external power supply to ON.
