ADA4805-1ARJZ-R7

ADA4805-1 is a high speed voltage feedback, rail-to-rail output amplifier with an exceptionally low quiescent current of 500µA, making them ideal for low power, high resolution data conversion systems. Despite being low power, these amplifiers provide excellent overall performance. 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. It is widely used in application such high resolution, high precision analogue-to-digital converter (ADC) drivers, battery-powered instrumentation, micropower active filters, portable point of sales terminals, active RFID readers, photo multipliers, ADC reference buffers etc.
