Overview
The AD8099ARD from Analog Devices Inc. is an ultralow noise and distortion voltage feedback operational amplifier. It is fabricated using Analog Devices' proprietary extra fast complimentary bipolar (XFCB) process, which enables high performance with relatively low power consumption. This op-amp is particularly suited for applications requiring high precision and low noise, such as 16- and 18-bit systems. It features a highly linear and low noise input stage, which enhances the full power bandwidth (FPBW) at low gains with high slew rates.
