The ADA4805-2-EP is a high speed voltage feedback, rail-to-rail output amplifier with an exceptionally low quiescent current of 500 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, a high slew rate of 160 V/µs, and a low input offset voltage of 125 µV (maximum).

The Analog Devices, Inc., proprietary extra fast complementary bipolar (XFCB) process allows both low voltage and low current noise (5.9 nV/√Hz, 0.6 pA/√Hz). The ADA4805-2-EP operates over a wide range of supply voltages from ±1.5 V to ±5 V, as well as single 3 V and 5 V supplies, making it ideal for high speed, low power instruments.

The ADA4805-2-EP is available in an 8-lead MSOP package and is rated to work over the extended industrial temperature range of −55°C to +125°C. Additional application and technical information can be found in the ADA4805-1/ADA4805-2 data sheet.
