The XTR115 and XTR116 are identical devices except for the reference voltage output, pin 1. This voltage is available for external circuitry and is not used internally. Further discussions that apply to both devices refer to the XTR11x.

Figure 8-1 shows basic circuit connections with representative simplified input circuitry. The XTR11x is a two-wire current transmitter. The device input signal (pin 2) controls the output current. A portion of this current flows into the V+ power supply, pin 7. The remaining current flows in Q₁. External input circuitry connected to the XTR11x can be powered from VREG or VREF. Current drawn from these terminals must be returned to IRET, pin 3. This IRET pin is a local ground for input circuitry driving the XTR11x.

Remote connections to current transmitters can sometimes be subjected to voltage surges. Best practice is to limit the maximum surge voltage applied to the XTR11x to as low as practical. Various Zener and surge clamping diodes are specially designed for this purpose. Select a clamp diode with as low a voltage rating as possible for best protection. For example, a 36-V protection diode provides proper transmitter operation at normal loop voltages, and also provides an appropriate level of protection against voltage surges. Characterization tests on several production lots showed no damage with loop supply voltages up to 65 V. Most surge protection Zener diodes have a diode characteristic in the forward direction that conducts excessive current, possibly damaging receiving-side circuitry if the loop connections are reversed. If a surge protection diode is used, also use a series diode or diode bridge for protection against reversed connections.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. Application Information B Changed Basic Circuit Connections application diagram yes The XTR115 and XTR116 are identical devices except for the reference voltage output, pin 1. This voltage is available for external circuitry and is not used internally. Further discussions that apply to both devices refer to the XTR11x. shows basic circuit connections with representative simplified input circuitry. The XTR11x is a two-wire current transmitter. The device input signal (pin 2) controls the output current. A portion of this current flows into the V+ power supply, pin 7. The remaining current flows in Q1. External input circuitry connected to the XTR11x can be powered from VREG or VREF. Current drawn from these terminals must be returned to IRET, pin 3. This IRET pin is a local ground for input circuitry driving the XTR11x. Basic Circuit Connections (1) Also see . (2) See . The XTR11x is a current-input device with a gain of 100. A current flowing into pin 2 produces IO = 100 • IIN. The input voltage at the IIN pin is zero (referred to the IRET pin). A voltage input is created with an external input resistor, as shown. Common full-scale input voltages range from 1 V and upward. Full-scale inputs greater than 0.5 V are recommended to minimize the effect of offset voltage and drift of A1. External Transistor B Changed External Transistor applications information section to incorporate additional guidance regarding transistor power dissipation and thermal concerns yes The external transistor, Q1, conducts the majority of the full-scale output current. Power dissipation in this transistor can approach 0.8 W with high loop voltage (40 V) and 20 mA of output current. The XTR11x is designed to use an external transistor to avoid on-chip, thermal-induced errors. Heat produced by Q1 still causes ambient temperature changes that can affect the XTR11x. To minimize these effects, locate Q1 away from sensitive analog circuitry, including the XTR11x. Mount Q1 so that heat is conducted to the outside of the transducer housing and away from the XTR11x. The XTR11x is designed to use virtually any NPN transistor with sufficient voltage, current, and power rating. Case style and thermal mounting considerations often influence the choice for any given application. Several possible choices are listed in . A MOSFET transistor does not improve the accuracy of the XTR11x and is not recommended. Although the XTR11x can be used without an additional external transistor, this configuration is not always practical at higher loop voltages and currents because of self-heating concerns. Minimum Scale Current The quiescent current of the XTR11x (typically 200 μA) is the lower limit of the device output current. Zero input current (IIN = 0 A) produces an IO equal to the quiescent current. Output current does not begin to increase until IIN > IQ / 100. Current drawn from VREF or VREG adds to this minimum output current. This means that more than 3.7 mA is available to power external circuitry while still allowing the output current to go below 4 mA. Offsetting the Input A low scale of 4 mA is produced by creating a 40-μA input current. This low-scale offset can be created with the proper value resistor from VREF (as shown in , or by generating offset in the input drive circuitry. Creating Low-Scale Offset Maximum Output Current The XTR11x provide accurate, linear output up to 25 mA. Internal circuitry limits the output current to approximately 32 mA to protect the transmitter and loop power or measurement circuitry. Extending the output current range of the XTR11x is possible by connecting an external resistor from pin 3 to pin 5 to change the current limit value. All output current must flow through internal resistors; therefore, damage is possible with excessive current. Output currents greater than 45 mA can cause permanent damage. Digital Control Methods Radio Frequency Interference The long wire lengths of current loops invite radio frequency interference (RF). RF can be rectified by the input circuitry of the XTR11x or preceding circuitry. This RF generally appears as an unstable output current that varies with the position of loop supply or input wiring. Interference can also enter at the input pins. For integrated transmitter assemblies with short connection to the sensor, the interference more likely comes from the current-loop connections. Circuit Stability B Added Circuit Stability application information section yes The 4-20 mA control-loop stability must be evaluated for any XTR11x design. A 10‑nF decoupling capacitor between V+ and IO is recommended for most applications. As this capacitance appears in parallel with the load resistance RLOAD from a stability perspective, the capacitor and resistor form a filter corner that can limit the bandwidth of the system. Therefore, for HART applications, use a bypass capacitance of 2 nF to 3 nF instead. For applications with EMI and EMC concerns, use a bypass capacitor with sufficiently low ESR to decouple any ripple voltage from the VLOOP supply. Otherwise, the ripple voltage couples onto the 4‑mA to 20‑mA current source, and appears as noise across RLOAD after the current-to-voltage conversion. Additionally, stability concerns apply to the VREF reference buffer when driving capacitive loads. shows that two filtering capacitors are required, one CHF of 10 pF to 0.5 µF and another CLF of 2.2 µF to 22 µF.

Figure 8-1 Basic Circuit Connections

The XTR11x is a current-input device with a gain of 100. A current flowing into pin 2 produces I_O = 100 • I_IN. The input voltage at the I_IN pin is zero (referred to the I_RET pin). A voltage input is created with an external input resistor, as shown. Common full-scale input voltages range from 1 V and upward. Full-scale inputs greater than 0.5 V are recommended to minimize the effect of offset voltage and drift of A1.
