## AD8614ART-R2: Overview and Technical Specifications The **AD8614ART-R2** is a high-speed, low-power operational amplifier (Op-Amp) manufactured by Analog Devices. It is designed for applications requiring high performance in a compact footprint, specifically featuring a "Rail-to-Rail" output swing. --- ### Core Specifications | Parameter | Specification | | :--- | :--- | | **Number of Channels** | 1 (Single Op-Amp) | | **Bandwidth (Gain Bandwidth Product)** | 40 MHz | | **Slew Rate** | 40 V/µs | | **Supply Voltage Range** | +5V to +18V (or ±2.5V to ±9V) | | **Supply Current (per channel)** | 800 µA (Typical) | | **Input Offset Voltage** | 1 mV (Maximum) | | **Output Type** | Rail-to-Rail | | **Package / Case** | SOT-23-5 | --- ### Key Electronic Features 1. **High Speed vs. Low Power:** The AD8614 is unique because it offers a significant bandwidth (40 MHz) and a high slew rate (40 V/µs) while consuming very little current (less than 1 mA). This makes it ideal for portable or battery-powered high-speed equipment. 2. **Rail-to-Rail Output:** The output signal can swing almost to the full range of the positive and negative supply rails. This maximizes the dynamic range, which is critical when working with low supply voltages. 3. **High Output Drive:** Despite its low power consumption, the part is capable of driving significant capacitive loads and providing high output current (up to 70 mA), which is useful for driving cables or filters. 4. **SOT-23-5 Packaging:** The "ART" in the part number denotes the SOT-23-5 package. This is a very small surface-mount package, saving board space in dense electronic designs. --- ### Typical Applications * **LCD Reference Drivers:** Used in display technology to provide stable reference voltages. * **Portable Instrumentation:** Due to the low power draw and high speed. * **Photodiode Amplifiers:** The high speed allows for rapid response to light changes. * **Active Filters:** Used in signal processing to remove noise without distorting the high-frequency components. --- ### Part Number Breakdown * **AD8614**: The base model number. * **ART**: Indicates the package type (SOT-23). * **R2**: Refers to the "Reel" size for automated manufacturing (7-inch reel containing 250 units).
