Description and Introduction

Single Supply 3V to 44V, Single Op Amp The MC34071 is a high-performance operational amplifier (op-amp) manufactured by Motorola (MOTO). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±1.5V to ±18V (Dual Supply) or 3V to 36V (Single Supply)  
- **Input Offset Voltage:** 1mV (Typical), 5mV (Maximum)  
- **Input Bias Current:** 30nA (Typical), 150nA (Maximum)  
- **Input Offset Current:** 5nA (Typical), 50nA (Maximum)  
- **Slew Rate:** 10V/µs (Typical)  
- **Gain Bandwidth Product:** 4.5MHz (Typical)  
- **Common-Mode Rejection Ratio (CMRR):** 100dB (Typical)  
- **Power Supply Rejection Ratio (PSRR):** 100dB (Typical)  
- **Output Current:** ±20mA (Short-Circuit Protected)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MC34071 is a single-channel operational amplifier with high gain, wide bandwidth, and low noise.  
- It is designed for applications requiring high performance, such as precision instrumentation, active filters, and data acquisition systems.  
- The device features JFET input stages for high input impedance and low input bias currents.  
- It is internally compensated for unity-gain stability.  

### **Features:**
- **Low Noise:** Suitable for sensitive signal processing.  
- **High Slew Rate:** Ensures fast response in dynamic applications.  
- **Wide Supply Voltage Range:** Supports both single and dual supply operations.  
- **Short-Circuit Protection:** Enhances reliability in harsh conditions.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Unity-Gain Stable:** No external compensation required.  

This information is based solely on the manufacturer's datasheet for the MC34071 op-amp.

Application Scenarios & Design Considerations

Single Supply 3V to 44V, Single Op Amp

Alternative Part Number

  • LM358N --: Widely available dual op-amp with similar general-purpose performance and pin-compatible DIP-8 footprint for many MC34071 applications.
  • TL071CP --: Low-noise JFET-input single op-amp offering comparable bandwidth and supply range, suitable as a functional substitute in many circuits.
  • NE5534AP --: High-performance low-noise single op-amp with similar supply voltage range and pinout, often used where MC34071 was specified.
  • OP07CP --: Precision single op-amp with low offset voltage and stable performance, suitable as a higher-accuracy replacement in circuits originally using the MC34071.
