- **Package Type:** SOIC-14 (DW suffix indicates wide-body SOIC package)  

### **Descriptions:**  
- The MC34084DW is a high-performance, low-noise, JFET-input quad operational amplifier.  
- It is designed for applications requiring wide bandwidth, high slew rate, and low input bias current.  
- Suitable for audio, signal conditioning, and precision instrumentation applications.  

### **Features:**  
- **JFET Input:** Provides high input impedance and low input bias current.  
- **Wide Supply Voltage Range:** Supports both single and dual supply operations.  
- **Low Noise:** Suitable for high-fidelity audio applications.  
- **High Slew Rate:** Ensures fast signal response.  
- **High CMRR:** Improves noise rejection in differential applications.  
- **ESD Protection:** Enhanced electrostatic discharge protection.  

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

Application Scenarios & Design Considerations

High Slew Rate, High Bandwidth, JFET Input Operational Amplifier

Alternative Part Number

  • LM324AD --: Quad operational amplifier in SOIC-14 with similar supply range and pinout; widely available and a common drop-in substitute for the MC34084.
  • TL074CD --: Quad low-noise JFET-input op-amp in SOIC-14; compatible pinout and supply voltage, suitable when lower input bias current is acceptable.
  • MC33074AD --: Quad op-amp from a different series with similar electrical characteristics and SOIC-14 package, offering a close functional replacement.
  • LF347D --: Quad JFET-input op-amp in SOIC-14 offering comparable performance and pinout, usable as a functional replacement.
