GENERAL DESCRIPTION
The AD9652 is a dual, 16-bit analog-to-digital converter (ADC) with sampling speeds of up to 310 MSPS. It is designed to support demanding, high speed signal processing applications that require exceptional dynamic range over a wide input frequency range (up to 465 MHz). Its exceptional low noise floor of −157.6 dBFS and large signal spurious-f...
