The ADA4805-1/ADA4805-2 are high speed voltage feedback,
rail-to-rail output amplifiers with an exceptionally low
quiescent current of 500 µA, making them ideal for low power,
high resolution data conversion systems. Despite being low
power, these amplifiers provide excellent overall performance.
They offer a high bandwidth of 105 MHz at a gain of +1, a high
slew rate of 160 V/µs, and a low input offset voltage of 125 µV
(maximum).
A shutdown pin allows further reduction of the quiescent
supply current to 2.9 µA. For power sensitive applications, the
shutdown mode offers a very fast turn-on time of 3 µs. This
allows the user to dynamically manage the power of the
amplifier by turning the amplifier off between ADC samples. Rev. B +7.5V
