The AD8646 is a dual, rail-to-rail, input and output, singlesupply amplifier featuring low offset voltage, wide signal bandwidth, low input voltage, and low current noise. 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.
