AD8655 Description

The AD8655 are the industry’s lowest noise, precision CMOS amplifiers. They leverage the Analog Devices DigiTrim® technology to achieve high dc accuracy.

The AD8655 provide low noise (2.7 nV/√Hz at 10 kHz), low THD + N (0.0007%), and high precision performance (250 μV max over VCM) to low voltage applications. The ability to swing rail-to-rail at the input and output enables designers to buffer analog-to-digital converters (ADCs) and other wide dynamic range devices in single-supply systems.

The high precision performance of the AD8655 improves the resolution and dynamic range in low voltage applications. Audio applications, such as microphone pre-amps and audio mixing consoles, benefit from the low noise, low distortion, and high output current capability of the AD8655 to reduce system level noise performance and maintain audio fidelity. The high precision and rail-to-rail input and output of the AD8655 benefit data acquisition, process controls, and PLL filter applications.

The AD8655 are fully specified over the −40°C to +125°C temperature range. The AD8655 are available in Pb-free, 8-lead MSOP and SOIC packages. The AD8655 are both available for automotive applications.
