EVM + PC

This chapter explains how to use the TLV320AIC3111 EVM with a PC running Windows XP.

To interface the TLV320AIC3111 EVM with a PC using USB, plug the TLV320AIC3111 EVM onto the
USB-MODEVM as shown in Figure 2 1. TLV320AIC3111 EVM + USB MODEVM.

Figure 1. TLV320AIC3111 EVM + USB MODEVM

Note:

USB-MODEVM configuration

To control the TLV320AIC3111 from the PC via the USB-MODEVM, set switch SW2 position
1, 3, 4, 5, 6, 7 to ON and position 2 and 8 to OFF.

•

Connect a headphone to J14 (3,5 mm jack)

•

Connect 8-

Ω

speakers to J8 and J9 (two 3-screw terminals)

–

Left speaker to SPLN and SPLP

–

Right speaker to SPRN and SPRP

•

By default, the on-board microphone is connected to the ADC. To use the line input (J7), refer to sheet
1 of the AIC3111_RHB_EVM schematics (chapter 3.2)

The TLV320AIC3111 control software exposes most features of the TLV320AIC3111 through an intuitive
graphical user interface.
