## Detailed Overview of TL082-S08-R The **TL082-S08-R** is a high-speed, dual JFET-input operational amplifier (Op-Amp). It is designed to offer a combination of high input impedance and low bias current, making it ideal for high-fidelity audio and precision signal processing. --- ### 1. Key Specifications The following table highlights the primary electrical and physical characteristics of this specific component: | Feature | Specification | | :--- | :--- | | **Number of Channels** | 2 (Dual Op-Amp) | | **Input Type** | JFET (High Impedance) | | **Package Type** | SOP-8 (Surface Mount) | | **Operating Voltage Range** | ±7V to ±18V (or 14V to 36V single supply) | | **Slew Rate** | 13 V/µs (Typical) | | **Gain Bandwidth Product** | 3 MHz to 4 MHz | | **Input Bias Current** | 30 pA (Typical) | | **Supply Current per Amp** | 1.4 mA | --- ### 2. Internal Block Diagram & Pinout The "S08" in the part number indicates an **SOP-8** package. The layout is standard for dual operational amplifiers: 1. **Pin 1:** Output A 2. **Pin 2:** Inverting Input A (-) 3. **Pin 3:** Non-inverting Input A (+) 4. **Pin 4:** Negative Supply ($V_{CC-}$ / GND) 5. **Pin 5:** Non-inverting Input B (+) 6. **Pin 6:** Inverting Input B (-) 7. **Pin 7:** Output B 8. **Pin 8:** Positive Supply ($V_{CC+}$) --- ### 3. Distinctive Advantages * **Low Input Bias/Offset Current:** Because it uses JFET technology at the input stage, the current "leaking" into the inputs is extremely low compared to Bipolar (BJT) op-amps like the LM358. * **High Slew Rate:** At 13 V/µs, it can handle rapid changes in signal voltage without distortion, which is essential for audio clarity. * **Low Harmonic Distortion:** Generally around 0.003%, making it a favorite for pre-amplifiers. * **Internal Frequency Compensation:** Simplifies circuit design as it does not require external capacitors to maintain stability. --- ### 4. Common Applications * **Audio Preamplifiers:** Used to boost low-level signals from microphones or instruments. * **Active Filters:** Ideal for high-pass, low-pass, and band-pass filters due to its wide bandwidth. * **Integrators and Differentiators:** Benefiting from the high input impedance. * **Sample and Hold Circuits:** The low bias current prevents the capacitor from discharging too quickly. --- ### 5.
