Chapter 2
Operation
The steps in this chapter can be followed to quickly prepare the TPA2008D2 stereo filter-free class-D audio amplifier EVM for use. Using the TPA2008D2 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. However, the audio amplifier evaluation module can be used stand-alone by making connections directly to the module pins, and can be wired directly into existing circuits or equipment.
The platform switch and jumper settings shown in Table 2–1 are typical for the TPA2008D2 EVM and causes the TPA2008D2 to shut down when a plug is in- serted into platform headphone jack J10.
Table 2–1. Typical TI Plug-N-Play Platform Jumper and Switch Settings for the TPA2008D2
EVM | JP4 | JP5 | JP6 | JP7 | JP8 | S2 | S3 |
| | | | | | | |
P-N-P Platform | X | ON | Mute | X | Lo | Note 2 | U5 |
Notes: 1) ON = Jumper installed, OFF = Jumper NOT Installed, X = Don’t care
2)Set S2 to ON when signal conditioning board is installed in U1; set S2 to OFF when no signal conditioning board is installed.
