The ADA4805-1 is a high speed voltage feedback rail-to-rail output amplifier with an exceptionally low quiescent current of 495 μA, making it 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 105 MHz at a gain of 1, 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 3 μA. For power sensitive applications, the shutdown mode offers very fast turn-on time of 3 μs from shutdown to fully on (output settled to 16 bits). 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 (5.9 nV/√Hz, 0.6 pA/√Hz). The ADA4805-1 operates over a wide range of supply voltages from ±1.5 V to ±5 V, as well as from single 3 V and 5 V supplies, making it ideal for high speed, low power instruments. The ADA4805-1 amplifier is available in both a 6-lead SOT-23 and a 6-lead SC70 package. These amplifiers are rated to work over the industrial temperature range of −40°C to +125°C.
