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.

2)Install a TPA6101A2 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.

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

Power supply

6)Select and connect the power supply:

7)Connect an external regulated power supply set to a voltage between 1.6

V and 3.6 V to platform VDD power input connector J6, taking care to ob- serve marked polarity,

or

8)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 to 12-V power

source to a platform VCC power input J1 or J2 and jumper the appropriate power input (see platform user’s guide). Set jumper JP1 on the SLVP097

-to 3.3-V operation.

Inputs and outputs

9)Ensure that signal source level is set to minimum and that potentiometers R1 and R4 are set to the midpoint.

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

-11) Connect 16-Ωto 32-Ωheadphones to headphone jack J10.

Power-up

12)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.
