ADA4806-1ARJZ-R2

ADA4806-1ARJZ-R2 is a high-speed, voltage feedback, rail-to-rail output, single operational amplifier. Despite being a low-power amplifier, this device provides excellent overall performance, making it ideal for low-power, high-resolution data conversion systems. For data conversion applications where minimizing power dissipation is paramount, this device offers a method to reduce power by dynamically scaling the quiescent power of the ADC driver with the sampling rate of the system by switching the amplifier to a lower power mode between samples. It is used in applications such as portable and battery-powered instruments and systems, high channel density data acquisition systems, precision analogue-to-digital converter (ADC) drivers, voltage reference buffers, portable point of sales terminals, and active RFID readers.
