Description and Introduction

Overvoltage-Protection Controllers with Internal FET The MAX4945AELA+ is a high-speed, low-power, quad SPST (Single-Pole Single-Throw) analog switch manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX4945AELA+  
- **Type:** Quad SPST Analog Switch  
- **Supply Voltage Range:** ±4.5V to ±20V (Dual Supply), +4.5V to +40V (Single Supply)  
- **On-Resistance (RON):** 100Ω (typical)  
- **On-Resistance Matching (ΔRON):** 5Ω (typical)  
- **Charge Injection:** 10pC (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Pin QSOP (EL)  

### **Descriptions:**  
The MAX4945AELA+ is designed for high-speed signal switching applications, offering low on-resistance and minimal charge injection. It is suitable for use in audio, video, and data acquisition systems.  

### **Features:**  
- Low On-Resistance (100Ω typical)  
- Low Charge Injection (10pC typical)  
- Wide Supply Voltage Range (±4.5V to ±20V dual, +4.5V to +40V single)  
- High Bandwidth (200MHz typical)  
- Fast Switching Times (tON = 100ns, tOFF = 50ns typical)  
- TTL/CMOS-Logic Compatible Control Inputs  
- Low Power Consumption  

This device is commonly used in signal routing, multiplexing, and switching applications where high performance and reliability are required.
