AD8655:  Low Noise, Precision CMOS Amplifier

Product Description

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.
