## Overview of the LM358L-P08-R The **LM358L-P08-R** is a specific variant of the widely used LM358 series. It is a **Low Power Dual Operational Amplifier** designed to operate from a single power supply over a wide range of voltages. ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Number of Channels** | 2 (Dual Op-Amp) | | **Supply Voltage (Single)** | 3V to 32V | | **Supply Voltage (Dual)** | ±1.5V to ±16V | | **Input Offset Voltage** | 2mV (Typical) | | **Gain Bandwidth Product** | 1.1 MHz | | **Slew Rate** | 0.6 V/μs | | **Package Type** | TSSOP-8 (typically indicated by P08 suffix) | | **Operating Temperature** | -40°C to +85°C (or 125°C depending on suffix) | --- ### Internal Circuitry and Part Features The LM358L-P08-R consists of two independent, high-gain, internally frequency-compensated operational amplifiers. 1. **Input Stage**: Utilizes a differential input stage that allows for common-mode sensing near the ground (negative rail). 2. **Output Stage**: Designed to provide a large output voltage swing, typically from 0V to $V_{CC} - 1.5V$. 3. **Power Consumption**: The "L" in the part number often signifies a lower power or specific low-voltage optimization compared to the standard LM358, making it ideal for battery-operated devices. --- ### Pin Configuration (TSSOP-8) | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | OUTPUT 1 | Output of the first amplifier | | 2 | IN 1 (-) | Inverting input of the first amplifier | | 3 | IN 1 (+) | Non-inverting input of the first amplifier | | 4 | GND / $V_{EE}$ | Ground or negative power supply | | 5 | IN 2 (+) | Non-inverting input of the second amplifier | | 6 | IN 2 (-) | Inverting input of the second amplifier | | 7 | OUTPUT 2 | Output of the second amplifier | | 8 | $V_{CC}$ | Positive power supply | --- ### Typical Applications * **Transducer Amplifiers**: Boosting signals from sensors like thermistors or pressure sensors. * **DC Gain Blocks**: Providing simple voltage amplification in DC circuits. * **Comparators**: Used in threshold detection for battery chargers or level sensors. * **Active Filters**: Implementing low-pass or high-pass filters in audio or signal processing.
