The **AD8014ARTZ-R2** is a high-speed, current feedback amplifier manufactured by Analog Devices. It is designed for applications requiring high bandwidth, low power consumption, and high output drive capability. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the AD8014: | Parameter | Specification | | :--- | :--- | | **Type** | Current Feedback Amplifier | | **Bandwidth (-3 dB)** | 480 MHz (G = +1) | | **Slew Rate** | 460 V/µs | | **Supply Voltage Range** | +4.5V to +12V (or ±2.25V to ±6V) | | **Supply Current** | 1.15 mA (Low Power) | | **Output Current** | 50 mA | | **Package Type** | SOT-23-5 (ARTZ designates this package) | --- ### 2. Core Features and Functionality * **Current Feedback Architecture:** Unlike traditional voltage feedback op-amps, the AD8014 uses current feedback. This allows for a very high slew rate and a closed-loop bandwidth that is relatively independent of the gain. * **Low Power Consumption:** Despite its high speed, it draws only 1.15 mA of quiescent current, making it ideal for battery-powered or high-density portable electronics. * **High Drive Capability:** It can drive up to 50 mA of load current with minimal distortion, which is excellent for driving video cables or capacitive loads. * **Low Distortion:** It maintains high signal integrity, which is critical for professional video and communications equipment. --- ### 3. Pin Configuration (SOT-23-5) The **ARTZ** suffix refers to the 5-lead SOT-23 package. The typical pinout is as follows: 1. **Vout:** Output of the amplifier. 2. **V-:** Negative Supply Voltage. 3. **+IN:** Non-inverting Input. 4. **-IN:** Inverting Input. 5. **V+:** Positive Supply Voltage. --- ### 4. Typical Applications The AD8014 is commonly found in the following electronic systems: * **Video Line Drivers:** Due to its high bandwidth and output drive. * **A/D Driver:** Serving as a buffer for high-speed Analog-to-Digital converters. * **IF/RF Amplification:** Used in communication signal chains. * **Active Filters:** High-speed filtering in instrumentation. --- ### 5. Part Number Breakdown (AD8014ARTZ-R2) * **AD8014:** Base model number. * **A:** Performance grade. * **RT:** Package designator (SOT-23). * **Z:** RoHS Compliant (Lead-free). * **R2:** Reel size/quantity (typically 250 units on a 7" reel).
