The AD8646, AD8647, and AD8648 are dual, dual, and quad, rail-to-rail input and output, single-supply amplifiers with low offset voltage, wide signal bandwidth, low input voltage, and low current noise, respectively. The AD8647 also features a low-power shutdown feature.
The combination of 24 MHz bandwidth, low offset, low noise, and extremely low input bias current characteristics makes these amplifiers suitable for a wide range of applications. Devices such as filters, integrators, photodiode amplifiers, and high-impedance sensors can benefit from this combination of characteristics. Wide bandwidth and low distortion are beneficial for AC applications. The AD8646/AD8647/AD8648 all feature high output drive capability, making 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 telephone headsets, barcode scanners, and multipolar filters. It also features rail-to-rail input and output swing capability, allowing designers to buffer CMOS ADCs, DACs, ASICs, and other wide-output swing devices in a single power supply system.
