2.4 Jumper Information

J1: Short this jumper to bias the EN pin to midsupply.

J_PD_SEL: This jumper connects to the power-down pin (PD) of the device. To power down the device using this jumper, short pins 1 and 2. To enable the device, short pins 2 and 3 of J_PD_SEL.

J_MODE_SEL: This jumper toggles between the high-current and low-current modes. Shorting pins 1 and 2 enables high-current mode. Shorting pins 2 and 3 enables low-current mode.

J_RBIAS_CTRL: This jumper sets the constant bias current using resistor R28. To enable the constant bias current, short pins 2 and 3. To disable this bias feature, short pins 1 and 2.
