Description and Introduction

3-Terminal Adjustable Current Source The LM234H is a precision current source manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Output Current Range:** Programmable from 1µA to 10mA  
- **Initial Accuracy:** ±3%  
- **Temperature Coefficient:** 6ppm/°C (typical)  
- **Operating Voltage Range:** 1V to 40V  
- **Operating Temperature Range:** -25°C to +100°C  
- **Package:** TO-46 metal can  

### **Descriptions:**  
The LM234H is a three-terminal adjustable current source designed to provide a highly stable output current over a wide voltage and temperature range. It operates as a true floating current source, requiring only an external resistor to set the output current.  

### **Features:**  
- **Precision Current Source:** Highly stable and accurate current regulation.  
- **Wide Operating Range:** Functions from 1V to 40V.  
- **Low Temperature Drift:** Excellent thermal stability (6ppm/°C typical).  
- **Simple Programmability:** Output current set by a single external resistor.  
- **True Two-Terminal Operation:** Can be used as a floating current source.  
- **Robust Packaging:** TO-46 metal can for durability and thermal performance.  

This information is based on the manufacturer's datasheet for the LM234H.
