SBOU034B February 2006 – October 2025 XTR300
A reference voltage is needed to produce a bidirectional output from a single-ended source. The XTR300EVM supports using either an external or onboard 5V reference voltage. To use the onboard reference voltage, shunt J7.
To use an external reference voltage, apply the voltage to terminal block TB2. Before applying the external reference voltage, make sure that shunt J7 is removed.
