Description and Introduction

4-20mA Current Transmitters with Sensor Excitation and Linearization The XTR112U is a precision voltage-to-current converter manufactured by Texas Instruments (TI)/Burr-Brown (BB). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 7.5V to 36V  
- **Output Current Range:** 4mA to 20mA (standard loop current)  
- **Input Voltage Range:** ±10V (differential)  
- **Reference Voltage Outputs:** 2.5V and 5V (precision references)  
- **Accuracy:** High linearity (0.002% typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-16  

### **Descriptions:**
The XTR112U is a 4-20mA current loop transmitter designed for industrial process control applications. It converts a differential input voltage into a proportional 4-20mA output current, suitable for long-distance signal transmission with minimal noise interference. The device includes integrated precision voltage references and excitation current sources for RTD (Resistance Temperature Detector) sensors.

### **Features:**
- **Voltage-to-Current Conversion:** Converts differential input voltage to 4-20mA output.  
- **Integrated References:** Provides 2.5V and 5V precision references for sensor excitation.  
- **RTD Excitation Current Sources:** Includes matched 200µA and 400µA current sources for RTDs.  
- **Wide Supply Range:** Operates from 7.5V to 36V, suitable for loop-powered applications.  
- **High Accuracy:** Low nonlinearity (0.002%) and low drift.  
- **Protection Features:** Reverse polarity and overvoltage protection.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
