The **AD8033AKS-R2** is a high-performance, low-power voltage feedback amplifier belonging to Analog Devices' *FastFET* family. It is designed to bridge the gap between high-speed performance and low power consumption, making it ideal for battery-operated instrumentation. --- ### 1. Key Technical Specifications The following table highlights the primary electrical characteristics of the AD8033AKS-R2: | Parameter | Specification | | :--- | :--- | | **Type** | FastFET Voltage Feedback Op-Amp | | **Number of Channels** | 1 (Single) | | **Bandwidth (-3 dB)** | 80 MHz | | **Slew Rate** | 80 V/µs | | **Supply Voltage Range** | 5V to 24V (Single) or ±2.5V to ±12V (Dual) | | **Supply Current** | 3.3 mA (Typical) | | **Input Bias Current** | 1 pA (Typical) | | **Package Type** | SC70-5 (Small Outline Transistor) | --- ### 2. Core Features * **FET Input Technology:** By using a Junction Field Effect Transistor (JFET) input stage, the device achieves extremely low input bias currents (pA range). This is critical for high-impedance sensor interfacing. * **Rail-to-Rail Output:** The output swing can reach within millivolts of the supply rails, maximizing the dynamic range, especially in low-voltage systems. * **High Speed vs. Low Power:** It offers a high gain-bandwidth product (80 MHz) while consuming significantly less power than traditional high-speed amplifiers. * **Wide Supply Range:** Unlike many high-speed CMOS op-amps limited to 5V, this part can handle up to 24V, allowing for more headroom in industrial applications. --- ### 3. Pinout Configuration (SC70-5) The AD8033AKS-R2 utilizes a standard 5-lead SC70 package: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | **OUT** | Amplifier Output | | 2 | **V-** | Negative Supply (or Ground) | | 3 | **+IN** | Non-Inverting Input | | 4 | **-IN** | Inverting Input | | 5 | **V+** | Positive Supply | --- ### 4. Typical Applications * **Photodiode Preamps:** Due to the low input bias current. * **Filters:** High-speed active filters in communication equipment. * **ADC Drivers:** Buffering signals for high-resolution Analog-to-Digital Converters. * **Instrumentation:** Portable medical and industrial measurement devices. --- ### 5.
