XTR115UA/2K5: High Precision Current Loop Transmitter for Industrial Automation

In the field of modern industrial automation and process control, 4-20mA current loop has become the standard way to transmit analogue signals. This method is widely used because of its strong anti-interference ability and long transmission distance. As an important component in this field, Texas Instruments' XTR115UA/2K5 has become the preferred choice of many engineers and purchasers due to its high accuracy and low power consumption.

Product Overview

The XTR115UA/2K5 is a precision 4-20mA current loop transmitter in a SOIC-8 package containing 2500 chips per reel. It is suitable for industry-standard two-wire current loop transmission and is capable of reliably converting analogue signals into standard current signals. Its built-in 2.5V reference voltage and 200μA ultra-low quiescent current design provide a perfect balance between performance and power consumption.

Core Features

- Low power design: Only 200μA quiescent current for low power applications.

- Precision voltage reference: Built-in 2.5V reference voltage provides stable excitation for external sensors.

- On-chip regulator: Integrated 5V regulator to power external circuits and simplify system design.

- High Accuracy:

  - Range error is only 0.05%.

  - Non-linear error as low as 0.003%.

- Wide operating range: Supports loop supply voltages from 7.5V to 36V, adapting to a variety of industrial environments.

- Industrial temperature range: stable operation from -40°C to +85°C.

Typical Applications

The XTR115UA/2K5 is widely used in the following areas:

- Industrial process control: monitoring and control of parameters such as pressure, temperature, and flow rate.

- Smart transmitters: Providing the base module for smart sensors.

- Test system: suitable for high-precision data acquisition and signal transmission.

- Compatible with HART modems: Supports industrial communication protocols through the external connection of HART modem modules.

Advantage analysis

As a high-performance current loop transmitter, the XTR115UA/2K5 not only meets demanding industrial requirements, but also reduces system complexity through its highly integrated design. Its low power consumption makes it particularly suitable for scenarios that require long periods of continuous operation. In addition, its wide operating temperature range and high reliability provide protection for applications in harsh environments.

Comparison with other models

There are other models in the XTR115 series, such as the XTR116 and the XTR117. In comparison, the XTR116 provides a more accurate reference voltage, while the XTR117 supports a wider range of input signals. Depending on the specific needs, customers can choose the model that best suits their application scenario.
