Description and Introduction

Single/Dual/Quad, 10MHz Single-Supply Op Amps The MAX473CUA is a precision, low-power, single-supply, SPST analog switch manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX473CUA  
- **Package:** 8-pin µMAX (microMAX)  
- **Switch Type:** Single-Pole Single-Throw (SPST)  
- **Supply Voltage Range:** +2.7V to +12V (single supply)  
- **On-Resistance (RON):** 25Ω (typical)  
- **On-Resistance Matching:** 4Ω (typical)  
- **Charge Injection:** 10pC (typical)  
- **Leakage Current (OFF State):** 1nA (typical)  
- **Switching Time (tON/tOFF):** 150ns / 100ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX473CUA is a precision, low-voltage, CMOS analog switch designed for high-performance signal switching.  
- It features low on-resistance, fast switching speeds, and minimal charge injection.  
- Suitable for battery-powered and portable applications due to its low power consumption.  
- The device is available in a space-saving 8-pin µMAX package.  

### **Features:**  
- Low On-Resistance (25Ω typical)  
- Single-Supply Operation (+2.7V to +12V)  
- Low Power Consumption (0.5µW typical)  
- Fast Switching Speeds (tON = 150ns, tOFF = 100ns)  
- Low Charge Injection (10pC)  
- High Off-Isolation (> -80dB at 1MHz)  
- TTL/CMOS-Logic Compatible

Application Scenarios & Design Considerations

Single/Dual/Quad, 10MHz Single-Supply Op Amps

Alternative Part Number

  • LTC1043CSW#PBF --: Pin-compatible switched-capacitor building block from Linear Technology (now ADI) with similar function and supply range, widely available as a MAX473 substitute.
  • ICL7660SCPA --: Classic switched-capacitor voltage converter in DIP-8 with comparable operating voltage and current capability, a common drop-in style replacement for MAX473 designs.
  • TC7660CPA --: Low-cost charge-pump voltage converter in PDIP-8 offering similar conversion functionality and supply range, suitable as a functional alternative.
  • LTC1043CSW --: Switched-capacitor building block usable as a charge-pump inverter/voltage converter, functionally similar to the MAX473 in many divider/inverter applications.
  • ADG201HSJN --: Quad SPST analog switch with comparable on-resistance and supply range, usable as a drop-in functional replacement in many MAX473 sockets.
  • DG201ACJ --: Classic quad SPST analog switch with similar switching characteristics and pin-compatible DIP footprint, offering a low-cost second source.
