Description

TheADA4805-1/ADA4805-2 are high speed voltage feedback, rail-to-rail output amplifiers with an exceptionally low quiescent current of 500 µA, making them ideal for low power, high resolution data conversion systems. Despite being low power, these amplifiers provide excellent overall performance. They offer 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).A shutdown pin allows further reduction of the quiescent supply current to 2.9 µA. For power sensitive applications, the shutdown mode offers a very fast turn on time of 3 µs. 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/ADA4805-2 operate 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 them ideal for high speed, low power instruments.The ADA4805-1 is available in a 6-lead SOT-23 and a 6-lead SC70 package. The ADA4805-2 is available in an 8-lead MSOP package. These amplifiers are rated to work over the industrial temperature range of −40°C to +125°C.ApplicationsHigh resolution, high precision analog-to-digital converter (ADC) driversBattery-powered instrumentationMicropower active filtersPortable point of sales terminalsActive radio frequency identification (RFID) readersPhoto multipliersADC reference buffers
