Description and Introduction

Low Voltage High Bandwidth Dual SPDT Switch The STG3682QTR is a high-speed, low-power, dual SPDT (Single Pole Double Throw) analog switch manufactured by STMicroelectronics.  

### **Key Specifications:**  
- **Configuration:** Dual SPDT (2 channels)  
- **Supply Voltage Range (VCC):** 1.8V to 5.5V  
- **Low On-Resistance (RON):** 0.5Ω (typical) at 4.5V  
- **Low Power Consumption:**  
  - Static Current: 0.1μA (max)  
  - Dynamic Current: 0.5μA (max)  
- **High-Speed Switching:**  
  - Turn-On Time (tON): 20ns (typical)  
  - Turn-Off Time (tOFF): 15ns (typical)  
- **Wide Bandwidth:** 200MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** QFN-10 (3x3mm)  

### **Description:**  
The STG3682QTR is designed for high-performance signal switching in portable and battery-powered applications. It features low on-resistance and fast switching speeds, making it suitable for audio, video, and data signal routing.  

### **Features:**  
- **Low Voltage Operation:** Supports 1.8V to 5.5V logic levels  
- **Break-Before-Make Switching:** Prevents signal shorting  
- **ESD Protection:** ±8kV (Human Body Model)  
- **Pb-Free & RoHS Compliant**  
- **Space-Saving Package:** QFN-10 for compact designs  

This switch is commonly used in smartphones, tablets, and other portable electronics for signal multiplexing and routing.
