The **UTL331L-AE5-R** is a specific low-power, low-voltage operational amplifier manufactured by UTC (Unisonic Technologies). It is designed to be functionally compatible with the industry-standard LMV331 series. --- ### 1. General Specifications Below are the primary technical parameters for the UTL331L-AE5-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | General Purpose Operational Amplifier / Comparator | | **Supply Voltage ($V_{CC}$)** | 2.7V to 5.5V | | **Supply Current** | ~40µA to 100µA (Low Power Consumption) | | **Package Type** | SOT-23-5 (AE5) | | **Mounting Type** | Surface Mount (SMD) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Pinout Configuration (SOT-23-5) The device follows the standard 5-pin configuration for small-signal operational amplifiers: 1. **IN+**: Non-inverting Input 2. **GND**: Ground (Negative Supply) 3. **IN-**: Inverting Input 4. **OUT**: Output 5. **VCC**: Positive Power Supply --- ### 3. Key Electronic Features * **Rail-to-Rail Input/Output:** This part is designed to handle signals that range from the negative rail (GND) to the positive rail ($V_{CC}$), making it ideal for low-voltage battery-operated devices. * **Low Quiescent Current:** It consumes very little power, which extends battery life in portable electronics. * **Space-Saving Design:** The SOT-23-5 package is extremely small, allowing for high-density PCB layouts. * **Open Collector Output:** (If used as a comparator variant) It allows for level shifting and wired-OR connections. --- ### 4. Part Number Decoding The suffix provides specific information about the packaging and material: | Suffix | Meaning | | :--- | :--- | | **AE5** | Indicates the **SOT-23-5** package style. | | **R** | Indicates **Tape & Reel** packaging for automated assembly. | | **L** | Often indicates "Lead-Free" or "Low Voltage" depending on UTC's internal naming convention. | --- ### 5. Typical Applications * Mobile phones and tablets. * Battery-powered medical devices. * Voltage window comparators. * Signal conditioning for sensors.
