The **LM358G-S08-R** is a specific variant of the widely used LM358 operational amplifier. It is a dual-channel, low-power Op-Amp designed to operate from a single power supply over a wide range of voltages. ### 1. Part Number Breakdown Understanding the suffix is crucial for identifying the package and material properties: | Component | Description | | :--- | :--- | | **LM358** | Core device name (Dual Operational Amplifier) | | **G** | Halogen-free and RoHS compliant (Green) | | **S08** | Package type: **SOP-8** (Small Outline Package, 8 pins) | | **R** | Packaging style: **Tape & Reel** | --- ### 2. Key Technical Specifications The LM358 series is known for its versatility in battery-operated equipment. | Parameter | Value / Range | | :--- | :--- | | **Number of Channels** | 2 (Dual) | | **Supply Voltage (Single)** | +3.0V to +32V | | **Supply Voltage (Dual)** | ±1.5V to ±16V | | **Gain Bandwidth Product** | 1.1 MHz | | **Input Offset Voltage** | 2mV (typical) | | **Output Current per Channel** | 20mA to 40mA | | **Operating Temperature** | -40°C to +85°C | --- ### 3. Pin Configuration (SOP-8) The device follows the industry-standard pinout for dual Op-Amps: 1. **Output 1**: Output of the first amplifier. 2. **Inverting Input 1 (-)**: Negative input of the first amplifier. 3. **Non-inverting Input 1 (+)**: Positive input of the first amplifier. 4. **GND/V-**: Negative supply rail or ground. 5. **Non-inverting Input 2 (+)**: Positive input of the second amplifier. 6. **Inverting Input 2 (-)**: Negative input of the second amplifier. 7. **Output 2**: Output of the second amplifier. 8. **Vcc+**: Positive supply rail. --- ### 4. Distinctive Features * **Internal Frequency Compensation**: No external capacitors are required for stability. * **Large DC Voltage Gain**: Typically 100 dB. * **Common-mode Input Range**: Includes the negative rail (Ground), allowing direct sensing near 0V without a negative power supply. * **Low Power Consumption**: Ideal for portable electronics. ### 5. Common Applications Because the LM358 is an industry "workhorse," it is used in: * **Transducer Amplifiers**: Boosting signals from sensors. * **DC Gain Blocks**: Providing simple voltage amplification. * **Comparators**: Comparing two voltages in logic circuits. * **Active Filters**: Implementing low-pass or high-pass filters in audio or signal processing. ---
