ADI ADA4898-1YRDZ

The ADA4898 is an ultralow noise and distortion, unity-gain stable, voltage feedback op-amp, ideal for 16-bit and 18-bit systems, operating over a supply voltage range of ±5 V to ±16 V. It features a linear, low-noise input stage with internal compensation, enabling high slew rate and low noise. The ADA4898 offers wide supply voltage range, low offset voltage, and wide bandwidth, making it highly flexible and versatile. A built-in cancellation circuit reduces input bias current. The ADA4898 is available in an 8-lead SOIC package with an exposed metal pad, which improves power dissipation and heat spreading to the negative supply plane, significantly outperforming conventional plastic packages. The ADA4898 is rated for the -40°C to +105°C extended industrial temperature range.
