Jumper Position Jumper Description

W14 1-2 Connects AVDD_ADC to AVDD2 or an external +1.8V supply (through J17.3).

W15 Open Connects AVSS_REG to an external –2.5V supply (through J18.1). Do not connect if the charge pump is enabled.

W16 1-2 Connects AVDD_DAC to AVDD1 or an external +1.8V supply (through J17.3).

W17 1-2 Connects AVSS_DAC to AVSS1 or an external –1.8V supply (through J17.1).

W18 1-2 Connects AVDD_HP to AVDD1 or an external +1.8V supply (through J17.3).

W19 1-2 Connects AVSS_HP to AVSS1 or an external –1.8V supply (through J17.1).

W20 2-3 Connects I2C_ADDR0 to IOVDD or ground.

W21 2-3 Connects I2C_ADDR1 to IOVDD or ground.

W22 Open Connects GPIO1 to J4.2/P4.2.

W23 Open Connects GPIO2 to J4.6/P4.6.

W24 Installed Provides a means of measuring IOVDD current.

W25 Installed Provides a means of measuring DVDD current.

W26 1-2 Connects DVDD to +1.8VD (provided by P3.7/J3.7) or an external +1.8V supply (through J17.3).

W27 Open Provides a means to connect IOVDD to +1.8VD (provided by P3.7/J3.7) or an external +1.8V supply (through J17.3).

W28 1-2 Connects IOVDD to +3.3VD (provided by P3.9/J3.9) or the source provided by the W27 setting.

W29 N/A N/A

W30 Open When installed, connects J4.8/P4.8 to RESETB.

W31 Installed When installed, it selects onboard EEPROM as firmware source.

2.3 Analog Signal Connections

2.3.1 Analog Inputs

The analog input sources can be applied directly to terminal blocks J7, J8, J9 and J10 or input jacks J6

and J11. The connection details can be found in Appendix A.

2.3.2 Analog Output

The analog outputs are available from terminal blocks J13, J14, J15 and J16 or output jack J12. The

connection details can be found in Appendix A.

2.4 Digital Signal Connections

The digital inputs and outputs of the EVM can be monitored through P4 and P5. If external signals need to

be connected to the EVM, digital inputs must be connected via 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.

2.5 Power Connections

The TLV320AIC36EVM can be powered independently when being used in stand-alone operation or by

the USB-MODEVM when it is plugged onto the motherboard.
