### TL072L-S08-R Overview The **TL072L-S08-R** is a high-speed, dual JFET-input operational amplifier (Op-Amp). It is widely recognized for its low power consumption, high slew rate, and low input bias/offset currents. The "L" suffix typically denotes a low-power or specific lead-free variant, while "S08-R" refers to the package type and tape/reel packaging. --- ### 1. Key Technical Specifications | Parameter | Typical Value | | :--- | :--- | | **Type** | Dual JFET-Input Op-Amp | | **Supply Voltage (Vcc)** | ±3.5V to ±18V | | **Input Bias Current** | 30 pA (typical) | | **Slew Rate** | 13 V/µs | | **Gain Bandwidth Product** | 3 MHz | | **Package Type** | SOP-8 (Small Outline Package) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Pinout Configuration (SOP-8) The TL072L is a dual Op-Amp, meaning it contains two independent amplifiers within a single 8-pin package. | 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 terminal | | 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 terminal | --- ### 3. Core Features and Internal Design * **JFET Inputs:** The use of Junction Field-Effect Transistors at the input stage provides extremely high input impedance. This prevents the Op-Amp from loading down the previous stage of the circuit. * **Low Harmonic Distortion:** It maintains signal integrity, making it a favorite for audio pre-amplification. * **Internal Frequency Compensation:** The device is stable for unity-gain applications without needing external capacitors. * **Latch-Up Free Operation:** The internal design prevents the device from entering a "latch-up" state which could lead to component failure. --- ### 4. Typical Applications Due to its low noise and high speed, the TL072L-S08-R is commonly found in: 1. **Audio Preamplifiers:** Used in mixers and guitar pedals for clean signal boosting. 2. **Active Filters:** High-pass, low-pass, and band-pass filters where precision is required. 3. **Buffer Amplifiers:** Used to match high-impedance sources to low-impedance loads. 4. **Data Acquisition:** Signal conditioning for sensors. --- ### 5. Part Number Breakdown * **TL072**: The base model (Dual JFET Op-Amp). * **L**: Often indicates a specific low-power selection or Lead-Free/RoHS compliance (varies by manufacturer like UTC). * **S08**: SOP-8 surface mount package. * **R**: Tape and Reel packaging for automated PCB assembly.
