AD8655ARZ

The AD8655/AD8656 are precision CMOS amplifiers featuring industry-leading low noise. Both utilize DigiTrim technology to achieve high DC accuracy. The AD8655/AD8656 deliver low noise (2.7 nV/√Hz at 10 kHz), low THD+N (0.0007%), and high precision performance (maximum 250 μV over VCM) for low-voltage applications. Rail-to-rail input and output swing capability allows designers to buffer ADCs and other wide dynamic range devices in single-supply systems. In low-voltage applications, the high precision of the AD8655/AD8656 improves resolution and dynamic range. Audio applications such as microphone preamplifiers and mixing consoles benefit from the low noise, low distortion, and high output current capability of the AD8655/AD8656, reducing system-level noise and ensuring audio fidelity. The high precision and rail-to-rail input and output of the AD8655/AD8656 also benefit data acquisition, process control, and PLL filter applications. The AD8655/AD8656 are rated for a temperature range of -40°C to +125°C. The AD8655/AD8656 are available in lead-free, 8-lead MSOP and SOIC packages.
