Description and Introduction

JFET INPUT OPERATIONAL AMPLIFIERS The TL081CD is a JFET-input operational amplifier (op-amp) manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±5V to ±18V (dual supply) or 10V to 36V (single supply)  
- **Input Offset Voltage:** 3 mV (typical)  
- **Input Bias Current:** 30 pA (typical)  
- **Input Offset Current:** 5 pA (typical)  
- **Input Resistance:** 10^12 Ω (typical)  
- **Common-Mode Rejection Ratio (CMRR):** 86 dB (typical)  
- **Slew Rate:** 13 V/µs (typical)  
- **Gain Bandwidth Product:** 3 MHz (typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 8-Pin SOIC (TL081CD)  

### **Description:**
The TL081CD is a high-speed, low-noise JFET-input operational amplifier designed for general-purpose applications. It features a high input impedance, low input bias current, and wide bandwidth, making it suitable for precision analog circuits.  

### **Features:**
- **JFET-Input:** Provides high input impedance and low input bias current.  
- **Low Noise:** Suitable for sensitive signal processing.  
- **Wide Supply Range:** Operates with dual or single power supplies.  
- **High Slew Rate:** Ensures fast signal response.  
- **Internal Frequency Compensation:** No external components needed for stability.  
- **Short-Circuit Protection:** Improves reliability.  

The TL081CD is commonly used in audio amplifiers, active filters, integrators, and other analog signal processing applications.

Application Scenarios & Design Considerations

JFET INPUT OPERATIONAL AMPLIFIERS

Alternative Part Number

  • LF351D --: JFET-input single op-amp with similar bandwidth and input characteristics, available in SO-8 package, direct functional replacement for TL081CD.
  • MC34081D --: Single JFET-input operational amplifier in SO-8 with comparable slew rate and input bias current, suitable drop-in substitute.
  • OPA141AID --: Precision JFET-input single op-amp in SO-8 offering lower offset and similar supply range, a higher-performance alternative when cost allows.
