Description and Introduction

Dual-Output, Switch-Mode Regulator(+5V to +-15V or +-12V) The MAX743EWE is a switched-capacitor filter manufactured by Maxim Integrated. Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Manufacturer:**  
MAXIM (now part of Analog Devices)  

### **Specifications:**  
- **Type:** Switched-Capacitor Filter (Dual, 5th-Order Lowpass)  
- **Package:** 16-Wide SOIC (WE)  
- **Operating Voltage Range:** ±4.5V to ±8V (Dual Supply) or +9V to +16V (Single Supply)  
- **Cutoff Frequency Range:** 10Hz to 30kHz (Adjustable via External Clock)  
- **Clock-to-Cutoff Ratio:** 100:1 (Typical)  
- **Stopband Attenuation:** -80dB (Typical)  
- **Total Harmonic Distortion (THD):** -70dB (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX743EWE is a dual, 5th-order lowpass switched-capacitor filter designed for precision signal processing. It provides steep roll-off and low distortion, making it suitable for anti-aliasing, noise filtering, and data acquisition applications. The cutoff frequency is set by an external clock signal.  

### **Features:**  
- Dual 5th-order lowpass filter in a single IC  
- Adjustable cutoff frequency via external clock  
- Low THD and high stopband rejection  
- Operates with dual or single power supply  
- Low noise and high accuracy  
- 16-pin SOIC (WE) package  

This information is strictly factual from the available knowledge base.

Application Scenarios & Design Considerations

Alternative Part Number

  • LT1054CS8 --: Pin-compatible switched-capacitor voltage converter in SO-8 that can serve as a functional substitute for the MAX743 in many dual-output inverter applications.
  • ICL7662CPA --: Classic CMOS voltage converter offering similar inverting/dual-supply conversion function; widely available and often used as a drop-in alternative in legacy designs.
  • TC962CPA --: Switched-capacitor voltage converter with comparable input range and output capability, suitable as a cross-reference replacement where exact MAX743 features are not critical.
  • ICL7662CBA --: Classic CMOS voltage converter with similar inverting/doubling function and SO-8 package, widely available as a drop-in style alternative.
  • TC7662BCOA --: CMOS charge-pump voltage converter in SO-8 offering comparable conversion capability and a different series naming for easy distinction.
