Description and Introduction

+5V, Low-Power, 12-Bit Serial ADCs The MAX189AEWE is a product from Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

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

### **Part Number:**  
MAX189AEWE  

### **Description:**  
The MAX189AEWE is a high-efficiency, step-down DC-DC converter designed for low-power applications. It integrates a switching regulator with a low-dropout linear regulator (LDO) to provide a regulated output voltage.  

### **Key Features:**  
- **Input Voltage Range:** 4V to 28V  
- **Output Voltage:** Adjustable (via external resistors)  
- **Switching Regulator Output:** Up to 500mA  
- **LDO Output:** Up to 50mA  
- **High Efficiency:** Up to 95%  
- **Low Quiescent Current:** Typically 100µA  
- **Switching Frequency:** 300kHz  
- **Thermal Shutdown Protection**  
- **Overcurrent Protection**  
- **Available in 16-Pin Wide SO Package (SOIC-16)**  

### **Applications:**  
- Battery-powered devices  
- Portable equipment  
- Industrial and automotive systems  
- Distributed power supplies

Application Scenarios & Design Considerations

+5V, Low-Power, 12-Bit Serial ADCs

Alternative Part Number

  • LTC1052CN8 --: Precision low-offset operational amplifier with comparable offset voltage and drift, pin-compatible in many 8-pin designs and a well-known second source for MAX189-class precision op-amps.
  • OP07CP --: Industry-standard low-offset bipolar op-amp with similar offset voltage and noise performance, widely available and often used as a drop-in replacement for precision MAX189 applications.
  • ICL7650CPD --: Chopper-stabilized precision op-amp offering very low offset voltage, suitable where MAX189 ultra-low offset performance is required, though pinout and supply range should be verified.
  • AD7893ARZ-10 --: Pin-compatible 12-bit serial ADC with similar sampling performance and supply range, widely available as a direct functional substitute.
  • LTC1290CCSW --: 12-bit serial ADC with comparable architecture and interface, suitable replacement when layout allows minor pinout adaptation.
  • ADS7841E --: 12-bit serial ADC offering similar resolution and speed, cost-effective alternative for designs needing a drop-in style replacement.
