Description and Introduction

Dual-Output, PWM Switch-Mode Regulator (5V to ±15V or ±12V) The **MAX743EWE+** is a switched-capacitor filter manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Manufacturer:** MAXIM Integrated (Analog Devices)  

### **Specifications:**  
- **Type:** Switched-Capacitor Filter  
- **Function:** 5th-Order, Lowpass, Elliptic Filter  
- **Cutoff Frequency Range:** Programmable (via external clock)  
- **Clock-to-Cutoff Ratio:** 100:1  
- **Supply Voltage Range:** ±5V (dual supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (WSOIC)  

### **Descriptions:**  
- The MAX743EWE+ is a high-performance, lowpass switched-capacitor filter designed for precision signal conditioning.  
- It provides a sharp roll-off characteristic with minimal passband ripple, making it suitable for anti-aliasing and noise reduction applications.  
- The cutoff frequency is set by an external clock signal, allowing flexibility in system design.  

### **Features:**  
- **5th-Order Elliptic Response** – Ensures steep roll-off and stopband rejection.  
- **Low Noise & Distortion** – Optimized for high-quality signal processing.  
- **Single or Dual Supply Operation** – Supports ±5V or +5V configurations.  
- **Low Power Consumption** – Suitable for battery-powered applications.  
- **No External Components Required** – Minimal external circuitry needed for operation.

Alternative Part Number

  • LT1054CS8#PBF --: Pin-compatible switched-capacitor voltage converter/inverter in SO-8 that can serve as a functional substitute for the MAX743 in many inverting/regulating applications.
  • ICL7662CBA+T --: Classic CMOS voltage inverter in SO-8 with similar charge-pump topology, widely used as a drop-in style replacement for MAX-series converters.
  • TC7662BEOA --: SO-8 CMOS charge-pump voltage converter with comparable input range and current capability, offering a different series/prefix as a clear alternative.
  • ICL7662CBA+ --: Widely available CMOS voltage converter from the same manufacturer family, suitable for voltage inversion and doubling where the MAX743 is used.
  • TC7662BCOA --: Low-cost charge-pump voltage converter in SO-8 with comparable input range and output current, offering a different series as a drop-in style alternative.
