AD8656 is the industry's lowest noise, They are precision CMOS amplifiers. They leverage Analog Devices DigiTrim technology to achieve high dc accuracy.
The AD8656 suits low-voltage applications with low noise (2.7 nV/√Hz at 10 kHz), provides low THD + N (0.0007%) and high sensitivity performance (250 µV max. via VCM). Rail-to-rail conversion capability on input and output allows designers to buffer analog-to-digital converters (ADCs) and other wide dynamic range devices in single-supply systems.
AD8656's Its high-precision performance improves resolution and dynamic range in low voltage applications. Audio applications such as microphone preamplifiers and audio mixing consoles take advantage of the AD8656's low noise, low distortion, and high output current capability to reduce system-level noise performance and maintain audio fidelity. The AD8656's high precision and rail-to-rail input and output benefit data acquisition, process controls, and PLL filter applications.
