Description and Introduction

Level Meter Driver for 9 LEDs Here are the factual details about part LB1409 from Ic-phoenix technical data files:  

### **Manufacturer Specifications:**  
- **Part Number:** LB1409  
- **Manufacturer:** Sanyo (now part of ON Semiconductor)  
- **Type:** LED Bar Graph Driver IC  
- **Supply Voltage (Vcc):** 4.5V to 16V  
- **Output Current:** 10mA per segment (typical)  
- **Number of Outputs:** 9 (for driving 9-segment LED bar displays)  
- **Input Type:** Analog voltage (0V to Vcc)  
- **Package:** DIP (Dual In-line Package)  

### **Descriptions:**  
The LB1409 is a monolithic IC designed to drive 9-segment LED bar graph displays. It converts an analog input voltage into a corresponding illuminated LED bar length, making it useful for visual level indication in audio equipment, power meters, and other measurement systems.  

### **Features:**  
- **Linear LED Drive:** Each segment lights up sequentially based on input voltage.  
- **Wide Voltage Range:** Operates from 4.5V to 16V.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Built-in Reference Voltage:** Simplifies external circuit requirements.  
- **Direct LED Drive:** No additional transistors needed for standard LED segments.
