## Technical Overview of LMV358L-S08-R The **LMV358L-S08-R** is a low-voltage, rail-to-rail output operational amplifier (Op-Amp). It is widely used in portable electronic devices due to its power efficiency and small footprint. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Number of Channels** | Dual (2 Op-Amps in one package) | | **Supply Voltage Range** | 2.7V to 5.5V | | **Output Type** | Rail-to-Rail | | **Quiescent Current** | ~210 µA (Typical) | | **Gain Bandwidth Product** | 1 MHz | | **Package Type** | SOP-8 (S08) | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### 2. Electronic Characteristics #### A. Rail-to-Rail Output Unlike standard op-amps (like the LM358), the "LMV" series allows the output voltage to swing very close to the positive and negative supply rails. This is critical for low-voltage systems (e.g., 3.3V) where maximizing the dynamic range is necessary. #### B. Low Power Consumption Designed specifically for battery-operated devices, it consumes significantly less current than the traditional LM358. #### C. Input Common-Mode Range The input common-mode voltage range includes ground (V-), making it suitable for single-supply applications. --- ### 3.
