### ADA4841-2YCPZ-R7 Overview The **ADA4841-2YCPZ-R7** is a high-performance, dual-channel, low-power, rail-to-rail output operational amplifier (op-amp) manufactured by **Analog Devices**. It is specifically designed for high-resolution data acquisition systems that require both low noise and low power consumption. --- ### Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Number of Channels** | 2 (Dual) | | **Gain Bandwidth Product** | 80 MHz | | **Slew Rate** | 13 V/µs | | **Voltage Noise Density** | 2.1 nV/√Hz | | **Supply Voltage Range** | 2.7 V to 12 V (±1.35V to ±6V) | | **Supply Current** | 1.1 mA per amplifier | | **Output Type** | Rail-to-Rail | | **Package Type** | LFCSP-8 (Lead Frame Chip Scale Package) | --- ### Component Breakdown #### 1. Low Noise and Distortion The device features an exceptionally low input voltage noise of **2.1 nV/√Hz** at 100 kHz. This makes it ideal for buffering high-speed, high-resolution Analog-to-Digital Converters (ADCs), such as 16-bit or 18-bit SAR ADCs, where maintaining signal integrity is critical. #### 2. Power Efficiency Despite its high bandwidth (80 MHz), it consumes only **1.1 mA** of quiescent current per amplifier. This efficiency is vital for battery-powered medical instrumentation or portable industrial sensors. #### 3. Rail-to-Rail Output The output can swing very close to the supply rails, maximizing the dynamic range of the signal processing chain, which is essential when operating on low-voltage supplies (e.g., 3.3V). --- ### Part Number Nomenclature (ADA4841-2YCPZ-R7) | Suffix | Meaning | | :--- | :--- | | **ADA4841** | Base Model Number | | **-2** | Indicates a Dual-channel configuration | | **YCP** | Package Code for LFCSP (Lead Frame Chip Scale Package) | | **Z** | RoHS compliant (Lead-free) | | **R7** | 7-inch Tape and Reel packaging (typically 1,500 units) | --- ### Typical Applications * **ADC Drivers:** Driving high-speed SAR and Delta-Sigma ADCs. * **Precision Filters:** Active filter designs requiring high bandwidth and low noise. * **Portable Instrumentation:** Handheld multimeters or diagnostic tools. * **Medical Imaging:** Low-noise signal conditioning for ultrasound or X-ray sensors.
