AD8646ARMZ-REEL

24 MHz轨到轨放大器与关机选项 24 MHz Rail-to-Rail Amplifiers with Shutdown Option

GENERAL DESCRIPTION

The AD8646 and the AD8647 are the dual, and the AD8648 is the quad, rail-to-rail, input and output, single-supply amplifiers featuring low offset voltage, wide signal bandwidth, low input voltage, and low current noise. The AD8647 also has a low power shutdown function.

The combination of 24 MHz bandwidth, low offset, low noise, and very low input bias current makes these amplifiers useful in a wide variety of applications. Filters, integrators, photodiode amplifiers, and high impedance sensors all benefit from the combination of performance features. AC applications benefit from the wide bandwidth and low distortion. TheAD8646/AD8647/AD8648 offer high output drive capability, which is excellent for audio line drivers and other low impedance applications.
