Analog Devices Inc. AD9680 14-Bit, 1GSPS Dual ADC
Analog Devices Inc. AD9680 14-Bit, 1GSPS Dual Analog-to-Digital Converters are a high-speed device featuring the best noise and dynamic range performance in its class, enabling the trend for direct RF sampling. The breakthrough performance, bandwidth and integrated functionality of ADI's wideband RF data acquisition technology allows for better signal extraction in congested RF environments over a wider bandwidth than ever before. This ADI device has an on-chip buffer and sample-and-hold circuit designed for low power, small size, and ease of use. This device is designed for sampling wide bandwidth analog signals of up to 2GHz.
