Product Details
The AD8655/AD8656 are the industry’s lowest noise, precision CMOS amplifiers. They leverage the Analog Devices DigiTrim® technology to achieve high dc accuracy.
The AD8655/AD8656 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/AD8656 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/AD8656 to reduce system level noise performance and maintain audio fidelity. The high precision and rail-to-rail input and output of the AD8655/ AD8656 benefit data acquisition, process controls, and PLL filter applications.
The AD8655/AD8656 are fully specified over the −40°C to +125°C temperature range. The AD8655/AD8656 are available in Pb-free, 8-lead MSOP and SOIC packages. The AD8655/ AD8656 are both available for automotive applications.
