ADA4805-2ARMZ

The ADA4805-2ARMZ is a high speed voltage feedback rail-to-rail output dual Operational Amplifier with an exceptionally low quiescent current of 500µA, making them ideal for low power, high resolution data conversion systems. Despite being low power, this amplifier provides excellent overall performance. It offers a high bandwidth of 105MHz at a gain of +1, a high slew rate of 160V/µs and a low input offset voltage of 125µV (maximum). A shutdown pin allows further reduction of the quiescent supply current to 2.9µA. For power sensitive applications, the shutdown mode offers a very fast turn on time of 3µs. This allows the user to dynamically manage the power of the amplifier by turning the amplifier off between ADC samples. The Analog Devices, Inc., proprietary extra fast complementary bipolar (XFCB) process allows for both low voltage and low current noise (5.9nV/?Hz, 0.6pA/?Hz).
