GENERAL DESCRIPTION

The AD8045 is a unity gain stable voltage feedback amplifier with ultralow distortion, low noise, and high slew rate. With a spurious-free dynamic range of −90 dBc @ 20 MHz, the AD8045 is an ideal solution in a variety of applications, including ultrasound, ATE, active filters, and ADC drivers. ADI’s proprietary next generation XFCB process and innovative architecture enables such high performance amplifiers.
