3.3.4.2 Mute/Mode Select (JP6)
A 3-pin jumper header (JP6) on the platform, functioning as an SPDT switch,

input pin or the mode control input pin of the evaluation module.
J To mute the TPA0202 amplifier module using the control signal from
the platform headphone jack, jumper JP6 to
MUTE
J To 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
3.3.4.3 Mute/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-ended output
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.
