Description and Introduction

Dual and Quad Channel Micropower, Single Supply, Rail-to-Rail Input and Output (RRIO) Instrumentation Amplifiers The ISL28273FAZ is a dual operational amplifier (op-amp) manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Supply Voltage Range:** ±1.35V to ±18V (Dual Supply), 2.7V to 36V (Single Supply)  
- **Input Offset Voltage:** 250µV (Max)  
- **Input Bias Current:** 10pA (Typ)  
- **Gain Bandwidth Product (GBW):** 10MHz  
- **Slew Rate:** 4V/µs  
- **Quiescent Current:** 1.1mA per amplifier (Typ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**
- The ISL28273FAZ is a precision, low-noise, dual-channel operational amplifier designed for high-performance applications.  
- It features rail-to-rail input and output operation, making it suitable for single-supply systems.  
- The device is optimized for low power consumption while maintaining high speed and accuracy.  

### **Features:**
- **Rail-to-Rail Input/Output**  
- **Low Input Offset Voltage (250µV Max)**  
- **Low Noise (8nV/√Hz at 1kHz)**  
- **Low Input Bias Current (10pA Typ)**  
- **Wide Supply Range (2.7V to 36V Single Supply, ±1.35V to ±18V Dual Supply)**  
- **High Gain Bandwidth (10MHz)**  
- **Low Quiescent Current (1.1mA per Amp)**  
- **Stable with Capacitive Loads up to 300pF**  
- **Pb-Free, RoHS Compliant**  

This op-amp is commonly used in precision instrumentation, sensor signal conditioning, and battery-powered applications.  

(Note: Always verify datasheet details for the latest specifications.)

Application Scenarios & Design Considerations
