AD8655:  Low Noise, Precision CMOS Amplifier

Product Details

The AD8655 is a low noise, precision CMOS amplifier featuring rail-to-rail output. The ability to swing rail-to-rail at the input and output enables designers to buffer ADCs and other wide output swing devices in single-supply systems.

The AD8655 features ADI’s patented DigiTrim® technology to achieve high DC accuracy. The AD8655 is suitable for industrial instrumentation applications where noise and DC performance are critical.

The AD8655 is fully specified over the −40°C to +125°C temperature range. AD8655 is available in 8-lead MSOP and SOIC packages.

    Analog Filter Wizard 2.0
    The Analog Filter Wizard™ helps you design a low-pass, high-pass, band-pass or band-stop filter with actual op amps. It then simulates the filter’s performance with these op amps in real time. You can ask the tool to optimize for power, noise, or voltage range, and it will pick op amps and passive components appropriately. Or you can adjust the components manually yourself.
