Using The TPA0202 EVM With the Plug-N-Play Evaluation Platform

3.3.4.2Mute/Mode Select (JP6)

A 3-pin jumper header (JP6) on the platform, functioning as an SPDT switch, routes the control signal from the headphone jack to either the mute control input pin or the mode control input pin of the evaluation module.

JTo mute the TPA0202 amplifier module using the control signal from the platform headphone jack, jumper JP6 to MUTE

JTo switch the output mode of the TPA0202 amplifier between BTL and single-ended using the control signal from the platform headphone jack, jumper JP6 to MODE

3.3.4.3Mute/Mode Polarity Select (JP8)

A second 3-pin jumper header (JP8) on the platform selects the control signal polarity by connecting either the active-high or the active-low line from the headphone jack to jumper JP6.

-When JP6 is set to Mute, use the following JP8 settings for the TPA0202:

J To mute the TPA0202 amplifier module when a plug is inserted into the headphone jack, jumper JP8 to Hi (this is the typical setting).

J To mute the TPA0202 amplifier module until a plug is inserted into the headphone jack, jumper JP8 to Lo.

-When JP6 is set to Mode, use the following JP8 settings for the TPA0202:

J To switch the TPA0202 amplifier module to the single-endedoutput mode when a plug is inserted into the headphone jack, jumper JP8 to Hi (this is the typical setting).

J To switch the TPA0202 amplifier module to the BTL output mode when a plug is inserted into the headphone jack, jumper JP8 to Lo.
