XTR115 116 Basic circuit diagram connection

The output reference voltage VREF from the O pin is not utilized within the internal circuit; instead, it is provided to the external circuit. Similarly, the output voltage VREG is also supplied to the external circuit. All current return paths (IRET) are connected to the input circuit, where the IRET ends are equivalent to Io. The circuit operates within a range of 4 to 20 mA for Io, with IIN ranging from 40 to 200 µA, and VIN varying from 0.8 to 4 V.

The described circuit configuration features a dual-output system, where VREF and VREG serve as critical voltage references for external applications. The VREF output is designed to provide a stable reference voltage, ensuring that external components can operate reliably without being influenced by internal circuit variations. This design choice enhances the flexibility of the circuit, allowing it to interface seamlessly with a variety of external devices.

The VREG output serves a similar purpose, supplying a regulated voltage to external circuits that may require a specific operating voltage. This output is essential for maintaining consistent performance across different load conditions, thereby improving the overall robustness of the system.

The current return paths, denoted as IRET, are integral to the circuit's functionality. These paths are designed to manage the return current effectively, ensuring that the system remains stable and that the input circuit operates correctly. The IRET configuration is crucial for minimizing noise and interference, which can adversely affect the performance of sensitive electronic components.

The operational specifications indicate that the output current Io can vary between 4 mA and 20 mA, making it suitable for applications such as industrial sensors and actuators that require precise current control. The input current IIN has a range of 40 µA to 200 µA, indicating that the circuit is designed to handle a wide range of input signals while maintaining accuracy and efficiency. The input voltage VIN operates between 0.8 V and 4 V, providing the necessary voltage levels for proper circuit operation.
