The ADI ADA4805-1 shutdown pin allows further reduction of the quiescent supply current to 3μA. For power sensitive applications, the shutdown mode offers very fast turn-on time of 3μs from shutdown to fully on (output settled to 16bits). This allows the designers to dynamically manage the power of the amplifier by turning the amplifier off between ADC samples.
With ADI's proprietary extra fast complementary bipolar (XFCB) process, ADA4805-1 enables both low voltage and low current noise (5.9nV/√Hz, 0.6pA/√Hz). Operating over a wide range of supply voltages from ±1.5V to ±5V, as well as from single 3V and 5V supplies, ADA4805-1 is ideal for high speed, low power, high resolution data conversion systems such as battery-powered instrumentation, micropower active filters, portable point-of-sales terminals, active RFID readers, photomultipliers, ADC reference buffers, and high resolution, high precision ADC drivers.
Evaluation board ADA4805-1ARJZEBZ is designed to help designers evaluate high speed op amps and quickly prototype new op amp circuits and reduce design time.
