## Overview of the TL082BCP The **TL082BCP** is a high-speed, dual JFET-input operational amplifier (op-amp). It belongs to the TL08x family and is widely known for its high input impedance and low bias current, making it ideal for high-fidelity audio and precision signal processing. --- ### Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Input Type** | JFET (High Impedance) | | **Number of Channels** | 2 (Dual) | | **Supply Voltage Range** | ±3.5V to ±18V | | **Slew Rate** | 13 V/µs (Typical) | | **Gain Bandwidth Product** | 3 MHz | | **Input Bias Current** | 30 pA (Typical) | | **Input Offset Voltage** | 3 mV (Max for 'B' Grade) | | **Package Type** | PDIP-8 (Plastic Dual In-line Package) | --- ### Detailed Component Features 1. **"B" Grade Precision:** The "B" in TL082BCP signifies a higher precision grade. It features a lower input offset voltage compared to the standard TL082 or TL082A versions. 2. **JFET Inputs:** Because it uses Junction Field-Effect Transistors at the input stage, it draws almost no current from the source (pico-ampere range). This prevents loading errors in high-impedance circuits. 3. **High Slew Rate:** At 13 V/µs, this op-amp can respond quickly to rapid changes in input signals, which reduces distortion in audio applications. 4. **Internal Compensation:** It is internally frequency-compensated for unity-gain stability, meaning it won't oscillate easily when used as a simple buffer. --- ### Pinout Configuration (PDIP-8) | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | **OUTPUT A** | Output of the first amplifier | | 2 | **IN A-** | Inverting input of the first amplifier | | 3 | **IN A+** | Non-inverting input of the first amplifier | | 4 | **Vcc-** | Negative power supply (or Ground) | | 5 | **IN B+** | Non-inverting input of the second amplifier | | 6 | **IN B-** | Inverting input of the second amplifier | | 7 | **OUTPUT B** | Output of the second amplifier | | 8 | **Vcc+** | Positive power supply | --- ### Common Applications * **Audio Pre-amplifiers:** Used for tone controls and active filters due to low noise and high speed. * **Sample and Hold Circuits:** High input impedance ensures minimal voltage drop over time. * **High-Impedance Buffers:** Connecting sensors with high output resistance to low-resistance loads. * **Active Filters:** Implementing Butterworth, Chebyshev, or Linkwitz-Riley filters.
