ADA4805 High-Speed Amplifiers

Analog Devices ADA4805-1 / ADS4805-2 High-Speed Amplifiers are high-speed voltage feedback, rail-to-rail output amplifiers with an exceptionally low quiescent current of 500μA, making them ideal for low-power, high-resolution data conversion systems. Despite being low power, ADI ADA4805 amplifiers provide excellent overall performance. They offer 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. ADA4805-1 / ADA4805-2 operate over a wide range of supply voltages from ±1.5V to ±5V, as well as single 3V and 5V supplies, making them ideal for high speed, low power instruments.
