Description and Introduction

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The **MAX861IUA+** is a high-performance, low-power operational amplifier (op-amp) manufactured by **Maxim Integrated** (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **Maxim Integrated** (now part of Analog Devices)  

### **Specifications:**  
- **Supply Voltage Range:**  
  - Single Supply: **+2.5V to +5.5V**  
  - Dual Supply: **±1.25V to ±2.75V**  
- **Low Supply Current:** **1.1mA per amplifier (typical)**  
- **Low Input Offset Voltage:** **0.5mV (max)**  
- **Low Input Bias Current:** **1nA (max)**  
- **High Gain Bandwidth Product:** **5MHz (typical)**  
- **Slew Rate:** **2.5V/µs (typical)**  
- **Unity-Gain Stable:** Yes  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **8-pin µMAX (IUA)**  

### **Descriptions:**  
- The **MAX861IUA+** is a **precision, low-power, single-supply operational amplifier** designed for applications requiring high performance with minimal power consumption.  
- It is optimized for **battery-powered and portable devices** due to its low supply current and wide operating voltage range.  
- The op-amp features **rail-to-rail output swing**, making it suitable for single-supply systems.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Rail-to-Rail Output:** Ensures maximum dynamic range in single-supply applications.  
- **High Precision:** Low offset voltage and bias current improve accuracy.  
- **Wide Supply Range:** Supports both single and dual supplies.  
- **Unity-Gain Stable:** No external compensation required.  

This information is based solely on the manufacturer's datasheet and product documentation.

Application Scenarios & Design Considerations

Alternative Part Number

  • ADM8611ARJZ-1 --: Pin-compatible supervisory IC with similar voltage monitoring and reset functions, from a different series and manufacturer.
  • TPS3700DDCR --: Low-power voltage supervisor with comparable threshold and reset behavior, suitable drop-in for many MAX861 applications.
  • MCP1316MT-29FE/OT --: Compact voltage supervisor offering similar reset and monitoring features at a competitive price.
  • LTC1685CS8#PBF --: Low-power RS-485/RS-422 transceiver in SO-8 with similar supply range and function, pin-compatible with the MAX861 family.
  • SN65HVD3082EDR --: Widely available low-power RS-485 transceiver in SOIC-8, functionally equivalent and commonly used as a drop-in substitute.
  • ISL8485EIBZ --: RS-485/RS-422 transceiver in SOIC-8 with comparable data rate and supply voltage, suitable as an alternative with different naming.
