The AD8646, AD8647, and AD8648 are dual, dual, and quad, rail-to-rail inputs and outputs, respectively,Single-supply amplifier, with low offset voltage, wide signal bandwidth, low input voltage, and low current noise. The AD8647 also features a low power shutdown function.
The combination of 24 MHz bandwidth, low offset, low noise, and very low input bias current makes these amplifiers suitable for a variety of applications.filterDevices such as integrators, photodiode amplifiers, and high-impedance sensors can benefit from these feature combinations. The wide bandwidth and low distortion are beneficial for AC applications. The high output drive capability of the AD8646/AD8647/AD8648 makes them ideal for audio line drivers and other low impedance applications. The AD8646 and AD8648 can be used in automotive applications.
Applications include portable and low-power instrumentation, audio amplification for portable devices, portable phone headsets, barcode scanners, and multipole filters. Rail-to-rail input and output swing capability also allows designers to buffer CMOS ADC, DAC, ASIC, and other wide output swing devices in single-supply systems.
