Description and Introduction

Dual General-Purpose Operational Amplifier The MC1458DR is a dual general-purpose operational amplifier (op-amp) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Number of Channels:** 2 (Dual)  
- **Supply Voltage Range:** ±3V to ±18V (Dual Supply) or 6V to 36V (Single Supply)  
- **Input Offset Voltage:** 2mV (Typical), 6mV (Maximum)  
- **Input Bias Current:** 500nA (Maximum)  
- **Gain Bandwidth Product:** 1MHz (Typical)  
- **Slew Rate:** 0.5V/µs (Typical)  
- **Common Mode Rejection Ratio (CMRR):** 70dB (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The MC1458DR is a dual operational amplifier designed for general-purpose applications. It features internal frequency compensation, high gain, and wide bandwidth. It is suitable for use in analog circuits, signal conditioning, and amplification tasks.  

### **Features:**  
- Internally frequency compensated  
- Short-circuit protection  
- Low power consumption  
- Wide supply voltage range  
- High voltage gain  
- No latch-up  

This op-amp is commonly used in audio amplifiers, filters, comparators, and other analog signal processing applications.

Application Scenarios & Design Considerations

Dual General-Purpose Operational Amplifier

Alternative Part Number

  • LM358DR --: Dual op-amp in the same SOIC-8 package with similar supply range and pinout; widely available and often used as a lower-cost substitute for the MC1458.
  • NE5532DR --: Dual low-noise op-amp in SOIC-8 with compatible pinout and supply voltage range; offers better AC performance for audio and general-purpose circuits.
  • TL072CDR --: Dual JFET-input op-amp in SOIC-8 with the same pin configuration; suitable replacement when higher input impedance and lower bias current are acceptable.
  • RC4558DR --: Dual general-purpose op-amp in SOIC-8 with comparable gain-bandwidth and supply range; a common pin-compatible replacement for the MC1458.
