Quick Start List for Platform

2.2 Quick Start List for Platform

Follow these steps when using the TPA122 MSOP EVM with the TI Plug-N-Play Audio Amplifier Evaluation Platform (see the platform user's guide, SLOU011, for additional details). Numbered callouts for selected steps are shown in Figure 2±1 and details appear in Chapter 3.

-Platform preparations

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 TPA122 MSOP 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 Hi.

5)Set Hp source switch S3 to U5 to route the output signal to the headphone Jack (J10).

2)Set S2 to ON when signal conditioning board is installed in U1; set S2 to OFF when no signal conditioning board is installed.

-Power supply

6)Select and connect the power supply:

a)Connect an external regulated power supply set to a voltage between 2.5 V and 5.5 V to platform VDD power input connector J6, taking care

to observe marked polarity,

or

b)Install a 3-V to 5-V voltage regulator EVM (SLVP097 or equiv.) in platform socket U6. Install a 9-V battery in B1 or connect a 7 V ± 12

V power source to a platform VCC power input J1 or J2 and jumper the appropriate power input (see platform user's guide).

-Inputs and outputs

7)Ensure that signal source level is set to minimum.

8)Connect the audio source to left and right RCA phono jacks J3 and J5 or stereo miniature phone jack J4.

9)Connect 32-Ωheadphones to headphone jack J10.

-Power up

10)Verify correct voltage and input polarity and set the external power supply

to ON. If VCC and an onboard regulator EVM are used to provide VDD, set platform power switch S1 to ON.

Platform LED2 should light indicating the presence of VDD, and the evaluation modules installed on the platform should begin operation.

11) Adjust the signal source level as needed.
