Description and Introduction

4.5 Ohm Quad SPST Analog Switches in UCSP The MAX4737EUD+ is a low-voltage, single-supply, SPST analog switch manufactured by Maxim Integrated.  

### **Key Specifications:**  
- **Supply Voltage Range:** +1.8V to +5.5V  
- **Low On-Resistance:** 0.5Ω (typical at +5V supply)  
- **Low On-Resistance Flatness:** 0.1Ω (typical)  
- **Fast Switching Time:** tON = 20ns, tOFF = 10ns (typical)  
- **Low Power Consumption:** 0.1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-TSSOP  

### **Descriptions:**  
The MAX4737EUD+ is a precision, low-voltage, single-pole/single-throw (SPST) analog switch designed for high-performance signal switching applications. It offers low on-resistance, minimal distortion, and fast switching speeds, making it suitable for portable and battery-powered devices.  

### **Features:**  
- **Single-Supply Operation:** Works from +1.8V to +5.5V  
- **Low On-Resistance:** Ensures minimal signal attenuation  
- **High Off-Isolation:** -80dB at 1MHz  
- **Low Charge Injection:** Reduces glitches during switching  
- **Rail-to-Rail Signal Handling:** Supports full supply range signals  
- **TTL/CMOS-Compatible Logic Inputs:** Ensures easy interfacing with digital circuits  

This device is commonly used in audio switching, battery-powered systems, and precision signal routing applications.
