Description and Introduction

The 'Rail Splitter' Precision Virtual Ground The TLE2426CP is a precision virtual ground reference IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1/2 of the input supply voltage (V+ / 2)  
- **Input Voltage Range:** 4V to 40V  
- **Output Current:** Up to 20mA  
- **Line Regulation:** 0.3mV (typical)  
- **Load Regulation:** 0.3mV (typical)  
- **Temperature Coefficient:** 20ppm/°C (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The TLE2426CP is a "rail splitter" IC that generates a stable virtual ground at half the input supply voltage. It is commonly used in single-supply applications to create a reference point for analog circuits, eliminating the need for a dual power supply.  

### **Features:**  
- Provides a precision midpoint reference voltage  
- Low output impedance (0.2Ω typical)  
- High accuracy and stability  
- Low quiescent current (400µA typical)  
- Short-circuit protection  
- No external components required for basic operation  

This IC is widely used in audio circuits, signal conditioning, and other applications requiring a stable virtual ground.

Application Scenarios & Design Considerations

The 'Rail Splitter' Precision Virtual Ground

Alternative Part Number

  • LM4041CIZ-1.2 --: Precision 1.2V shunt voltage reference in TO-92, a common functional substitute for a 1.2V rail reference in through-hole designs.
  • ADR510ARTZ-REEL7 --: Low-noise 1.2V precision voltage reference with excellent stability, suitable where tighter accuracy than the TLE2426 is needed.
  • LT1004CZ-1.2 --: Classic 1.2V micropower shunt reference in TO-92, widely available and pin-compatible in many through-hole reference applications.
