Description and Introduction

Dual Operational Amplifiers The IL4558D is a dual operational amplifier (op-amp) integrated circuit. Below are its key specifications, descriptions, and features based on available factual information:

### **Manufacturer Specifications:**
1. **Supply Voltage Range:** ±3V to ±18V (dual supply) or 6V to 36V (single supply).  
2. **Input Offset Voltage:** Typically 2mV (max 6mV).  
3. **Input Bias Current:** Typically 50nA.  
4. **Input Offset Current:** Typically 5nA.  
5. **Common-Mode Rejection Ratio (CMRR):** 80dB (typical).  
6. **Slew Rate:** 1.5V/µs (typical).  
7. **Gain Bandwidth Product:** 3MHz (typical).  
8. **Output Voltage Swing:** Typically ±13V (with ±15V supply).  
9. **Operating Temperature Range:** -40°C to +85°C.  
10. **Package Type:** 8-pin DIP (Dual Inline Package) or SOIC (Small Outline IC).  

### **Descriptions:**
- The IL4558D is a general-purpose dual op-amp designed for a wide range of analog applications.  
- It is internally compensated for stable operation without external components.  
- Suitable for audio amplifiers, active filters, signal conditioning, and other analog circuits.  
- Compatible with the industry-standard 4558 op-amp series.  

### **Features:**
1. **Dual Op-Amp Configuration:** Contains two independent op-amps in a single package.  
2. **Low Noise:** Suitable for audio and precision signal processing.  
3. **Wide Supply Voltage Range:** Supports both single and dual power supplies.  
4. **Short-Circuit Protection:** Built-in protection against output short circuits.  
5. **High Input Impedance:** Minimizes loading effects on input signals.  
6. **Stable Performance:** Internally frequency-compensated for ease of use.  

The IL4558D is commonly used in consumer electronics, industrial control systems, and instrumentation circuits.

Application Scenarios & Design Considerations

Dual Operational Amplifiers

Alternative Part Number

  • RC4558D --: Industry-standard dual low-noise op-amp with the same pinout and function, widely available and a direct functional replacement.
  • NE5532D --: Dual low-noise op-amp in SOIC-8 with better noise and drive performance, commonly used as an upgrade for 4558-type audio circuits.
  • LM358D --: Dual op-amp in SOIC-8 with compatible pinout, suitable for general-purpose replacements where lower bandwidth is acceptable.
  • MC33078DR2G --: Dual low-noise op-amp in SOIC-8 with comparable or better specifications, suitable as a functional substitute for the IL4558D.
  • MC4558CD --: Dual op-amp in SOIC-8 with matching pinout and similar gain-bandwidth and supply range, a common second-source equivalent for 4558-type devices.
