12Bit, 2GSPS, 1.3V/2.5V Analog-to-Digital Converter
GENERAL DESCRIPTION
The AD9625 is a 12-bit monolithic sampling analog-to-digital converter ADC that operates at conversion rates of up to 2.0 giga samples per second GSPS. This product is designed for sampling wide bandwidth analog signals up to the second Nyquist zone. The combination of wide input bandwidth, high sampling rate, and excellent linearity of the AD9625 is ideally suited for spectrum analyzers, data acquisition systems, and a wide assortment of military electronics applications, such as radar and jamming/antijamming measures.
