ADA4817-1ARDZ 1 GHz Bandwidth Op Amp FET-Input Operational Amplifier
The ADA4817-1ARDZ from Analog Devices is a high-speed, low-noise operational amplifier that delivers exceptional performance for precision signal conditioning applications. Utilizing an advanced silicon-on-insulator (SOI) process with FET-input technology, this amplifier achieves a remarkable 1 GHz gain bandwidth product with ultra-low distortion characteristics. Packaged in an 8-lead SOIC, the device operates from ±5 V to ±6.5 V dual supplies, making it particularly suitable for high-speed data acquisition systems, medical imaging equipment, and test and measurement instruments where signal fidelity and bandwidth are critical. Its combination of high speed, low noise, and low power consumption establishes it as an ideal solution for driving analog-to-digital converters and processing high-frequency signals with minimal distortion.
Key Features & Applications
The amplifier features an input voltage noise of just 2 nV/√Hz at 10 MHz and current noise of 1 fA/√Hz, ensuring excellent signal integrity in sensitive applications. It provides a high slew rate of 950 V/μs and maintains low harmonic distortion of -95 dBc at 5 MHz, enabling accurate reproduction of fast-changing signals. The device's decompensated architecture requires a minimum gain of 10 for stable operation, while its rail-to-rail output stage maximizes dynamic range in low-voltage systems. Additional features include disable functionality for power management, thermal shutdown protection, and ESD robustness up to 4 kV, ensuring reliable performance in demanding environments across the industrial temperature range (-40°C to +125°C).
The ADA4817-1ARDZ excels in high-performance applications including ultrasound imaging systems, where its wide bandwidth and low noise characteristics enable precise signal amplification from transducers. It serves effectively in photodiode amplification circuits for LiDAR and optical communications, leveraging its high impedance and fast response capabilities. The amplifier is also widely used in automated test equipment, high-speed data converters, and communication infrastructure where signal integrity must be maintained at high frequencies.
