7.3.1 Reverse-Voltage Protection

The XTR11x low compliance voltage rating (7.5 V) permits the use of various voltage protection methods without compromising the operating range. Figure 7-2 shows a diode bridge circuit that allows normal operation even when the voltage connection lines are reversed. The bridge causes a two-diode drop (approximately 1.4 V) loss in loop supply voltage. This loss results in a compliance voltage of approximately 9 V—satisfactory for most applications. A diode can be inserted in series with the loop supply voltage and the V+ pin to protect against reverse output connection lines with only a 0.7-V loss in loop supply voltage.
