2.2.2 TLV320DAC3203 Jumper Locations

Table 2 provides a list of jumpers found on the EVM and their factory default conditions.

Table 2. List of Jumpers and Switches

Jumper Default Position Jumper Description

W1 1-2 Sets IOVDD to 3.3 V (default) or 1.8 V.

W2 2-3 Sets DIGMIC_PWR to 3.3 V (default) or 1.8 V.

W3 Removed Connects GPIO2 to RESET line.

W4 Installed Provides a means to measure LDOin/HPVDD current.

W5 Installed Provides a means to measure AVDD current. When using the internal LDO, this jumper should be

removed.

W6 Installed Provides a means to measure DVDD current.

W7 Installed Provides a means to measure IOVDD current.

W8 Removed Connects 16-Ω load to HPL outputs.

W9 Removed Connects 16-Ω load to HPR outputs.

W10 Removed When installed, shorts across the output capacitor on HPL; remove this jumper if using AC-coupled output

drive.

W11 Removed When installed, shorts across the output capacitor on HPR; remove this jumper if using AC-coupled output

drive.

W12 Removed When inserted, connects MICBIAS to J2.4 for headset detection use.

W13 Installed When installed, it selects onboard EEPROM as firmware source.

W14 2-3 When SW1 is configured for I

C, selects SCLK source for digital microphone or headset detection use.

W15 Installed Connects MISO to USB-MODEVM. Remove this jumper for digital microphone use.

SW1 Toward I

C When set to I

C, the I

C signals from P12/J12 are connected to the codec and SPI_SELECT is set low.

When set to SPI, the SPI signals from P12/J12 are connected to the codec and SPI_SELECT is pulled to

IOVDD.

2.3 Analog Signal Connections

2.3.1 Analog Inputs

Apply the analog input sources directly to terminal block J5 or input jack J4. The connection details are

found in Appendix A.

2.3.2 Analog Output

The analog outputs are available from terminal block J1 or output jacks J2 and J3. Note that J3 is

provided for signal-to-noise ratio (SNR) measurements only. The connection details are found in

Appendix A.

2.4 Digital Signal Connections

The digital inputs and outputs of the EVM are monitored through P12 and P22. If external signals are

connected to the EVM, digital inputs must be connected through J14 and J15 on the USB-MODEVM and

the SW2 switch must be changed accordingly (see Section 2.2.1). The connector details are available in

Section A.2.
