## AD8034ARTZ-R2: FastFET™ Operational Amplifier The **AD8034ARTZ-R2** is a high-speed, dual-channel, FET-input operational amplifier manufactured by **Analog Devices**. It belongs to the **FastFET™** family, designed to offer a balance between high speed, low noise, and low input bias current. --- ### 1. Key Technical Specifications Below are the primary electrical characteristics of the AD8034ARTZ-R2: | Parameter | Specification | | :--- | :--- | | **Architecture** | Dual Channel (FET Input) | | **Bandwidth (-3 dB)** | 80 MHz | | **Slew Rate** | 80 V/µs | | **Input Bias Current** | 2 pA (Typical) | | **Voltage Noise** | 11 nV/√Hz | | **Supply Voltage Range** | 5 V to 24 V (±2.5 V to ±12 V) | | **Supply Current** | 3.3 mA per amplifier | | **Output Type** | Rail-to-Rail | --- ### 2. Functional Features * **High Input Impedance:** Because it uses FET (Field-Effect Transistor) inputs, it has an extremely low input bias current (picoampere range), making it ideal for interfacing with high-impedance sensors. * **Speed and Agility:** With an 80 MHz bandwidth and high slew rate, it can handle fast signals without significant distortion. * **Rail-to-Rail Output:** The output can swing very close to the supply rails, maximizing the dynamic range, especially in low-voltage systems. * **Low Power Consumption:** Despite its high speed, it consumes relatively low current (3.3 mA), which is beneficial for portable or dense PCB designs. --- ### 3. Package and Ordering Information The suffix codes in the part number provide specific manufacturing details: * **ARTZ:** Refers to the **SOT-23 (6-lead)** package. This is a very small surface-mount package suitable for space-constrained applications. * **R2:** Indicates the reel size/quantity for automated assembly (typically a 7-inch reel containing 250 units). * **Lead-Free:** The "Z" denotes that the part is RoHS compliant (lead-free). --- ### 4. Common Applications Due to its unique combination of FET inputs and high speed, the AD8034 is frequently used in: 1. **Photodiode Preamps:** Converting light-induced current into voltage. 2. **Precision Filters:** High-speed active filters where low input bias is required. 3. **Data Acquisition:** Serving as a buffer for high-speed Analog-to-Digital Converters (ADCs). 4. **Instrumentation:** High-impedance signal conditioning. ---
