Description and Introduction

GENERAL PURPOSE QUAD JFET OP-AMPS The TL084ACD is a JFET-input operational amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Number of Channels:** 4  
- **Supply Voltage (VCC±):** ±18V (max)  
- **Input Offset Voltage:** 3 mV (typ), 6 mV (max)  
- **Input Bias Current:** 30 pA (typ), 200 pA (max)  
- **Input Offset Current:** 5 pA (typ), 100 pA (max)  
- **Gain Bandwidth Product:** 3 MHz (typ)  
- **Slew Rate:** 13 V/µs (typ)  
- **Common Mode Rejection Ratio (CMRR):** 86 dB (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-14  

### **Descriptions:**  
The TL084ACD is a high-speed JFET-input quad operational amplifier with low input bias current and offset current. It is designed for applications requiring high input impedance, low noise, and wide bandwidth. The device features internal frequency compensation and latch-up-free operation.  

### **Features:**  
- **Low Power Consumption:** 1.4 mA per amplifier (typ)  
- **Wide Common-Mode & Differential Voltage Range**  
- **Low Input Bias & Offset Currents**  
- **Output Short-Circuit Protection**  
- **Low Total Harmonic Distortion (THD):** 0.003% (typ)  
- **High Input Impedance:** 10^12 Ω (typ)  
- **Latch-Up-Free Operation**  
- **Internal ESD Protection**  

This information is based on TI's official datasheet for the TL084ACD.

Application Scenarios & Design Considerations
