AD8646:  24 MHZ RAIL-TO-RAIL DUAL AMPLIFIER

Product 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.

Applications include portable and low powered instrumentation, audio amplification for portable devices, portable phone headsets, barcode scanners, and multipole filters. The ability to swing rail to rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in single-supply systems.

Applications

  • Battery-powered instruments
  • Multipole filters
  • ADC front ends
  • Sensors
  • Barcode scanners
  • ASIC input or output amplifiers
  • Audio amplifiers
  • Photodiode amplifiers
  • Datapath/mux/switch control

    • Data Sheet, Rev. B, 10/07
