The **TL062L-S08-R** is a Low-Power JFET-input Dual Operational Amplifier (Op-Amp). It is part of the TL06x series, specifically designed for applications where power consumption is a primary concern. Below is a detailed breakdown of its specifications, pinout, and key features. --- ### 1. General Specifications | Parameter | Description | | :--- | :--- | | **Part Number Breakdown** | **TL062**: Dual Op-Amp | **L**: Lead-free/RoHS | **S08**: SOP-8 Package | **R**: Tape & Reel | | **Input Type** | JFET (High Input Impedance) | | **Number of Channels** | 2 (Dual) | | **Supply Voltage Range** | ±3.5V to ±18V | | **Supply Current** | ~200 µA per amplifier (Very Low) | | **Slew Rate** | 3.5 V/µs | | **Gain Bandwidth Product** | 1 MHz | --- ### 2. Pin Configuration (SOP-8) The TL062L-S08-R follows the standard dual op-amp pinout configuration: | Pin Number | Symbol | Function | | :--- | :--- | :--- | | 1 | **OUT1** | Output of Amplifier 1 | | 2 | **IN1-** | Inverting Input of Amplifier 1 | | 3 | **IN1+** | Non-inverting Input of Amplifier 1 | | 4 | **Vcc-** | Negative Power Supply / Ground | | 5 | **IN2+** | Non-inverting Input of Amplifier 2 | | 6 | **IN2-** | Inverting Input of Amplifier 2 | | 7 | **OUT2** | Output of Amplifier 2 | | 8 | **Vcc+** | Positive Power Supply | --- ### 3. Key Electronic Features #### A. High Input Impedance Because the inputs are **JFET (Junction Field-Effect Transistor)** based, the device has an extremely high input resistance ($10^{12} \Omega$ typical). This means it draws almost no current from the input source, making it ideal for high-impedance sensors. #### B. Low Power Consumption The "Low Power" designation refers to the quiescent current. It consumes significantly less power than the standard TL082 or TL072 series, making it suitable for battery-operated handheld devices. #### C. Internal Frequency Compensation The chip includes internal compensation, ensuring stability in closed-loop configurations without requiring external capacitors. --- ### 4. Typical Applications * **Battery-Powered Circuits:** Due to the low $I_{CC}$ (supply current). * **Active Filters:** High-order filters where precision and low power are needed. * **Preamplifiers:** Used in audio or sensor conditioning where high input impedance is required to prevent loading the source. * **Voltage Followers:** Buffering signals from high-impedance sources. --- ### 5. Equivalent/Alternative Parts If this specific part is unavailable, the following are common alternatives: 1. **TL072:** Low-noise version (higher power consumption). 2. **TL082:** General-purpose version (higher power consumption). 3. **LF353:** Wide bandwidth JFET input dual op-amp.
