Description and Introduction

2Ω, Quad, SPST, CMOS Analog Switches The MAX4678EUE+ is a high-speed, low-voltage, CMOS analog multiplexer/demultiplexer manufactured by Maxim Integrated.  

### **Key Specifications:**  
- **Configuration:** Dual 4:1 or single 8:1 multiplexer/demultiplexer  
- **Supply Voltage Range:** +2.7V to +12V (single supply) or ±2.7V to ±6V (dual supply)  
- **On-Resistance (RON):** 5Ω (typical)  
- **On-Resistance Flatness:** 1Ω (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Charge Injection:** 10pC (typical)  
- **Crosstalk Rejection:** -90dB (at 1MHz)  
- **Off-Isolation:** -90dB (at 1MHz)  
- **Switching Time (tON/tOFF):** 20ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-TSSOP  

### **Descriptions & Features:**  
- **Low On-Resistance:** Ensures minimal signal distortion.  
- **Wide Voltage Range:** Supports both single and dual supply operation.  
- **High Bandwidth:** Suitable for high-speed signal switching.  
- **Low Charge Injection:** Reduces glitches during switching.  
- **Low Crosstalk & High Off-Isolation:** Improves signal integrity.  
- **Break-Before-Make Switching:** Prevents signal overlap.  
- **TTL/CMOS-Logic Compatible:** Easy integration with digital control circuits.  

The MAX4678EUE+ is commonly used in communication systems, test equipment, and data acquisition systems requiring fast, low-distortion signal switching.

Application Scenarios & Design Considerations

2Ω, Quad, SPST, CMOS Analog Switches

Alternative Part Number

  • ADG1611BRUZ --: Quad SPST analog switch with similar low on-resistance and TSSOP-16 package, direct functional replacement.
  • DG411DJZ --: Quad SPST analog switch offering comparable signal switching performance and pin-compatible layout options.
  • TS5A23157DGSR --: Low-voltage dual SPDT analog switch usable as a substitute in similar signal routing applications.
  • TS3A4751PWR --: Low-voltage quad SPST switch with similar RON characteristics, suitable alternative when package adaptation is acceptable.
