Analog Devices AD9680 14-Bit Dual ADC Evaluation Board

ADI AD9680 14-Bit Dual ADC Evaluation Board

Analog Devices AD9680 Evaluation Board is a development tool for the AD9680 dual, 14-bit, 1000MSPS analog-to-digital converter (ADC). ADI AD9680 ADC is designed for sampling wide bandwidth analog signals of up to 2GHz. The ADC is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package. The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. The analog input and clock signals are differential inputs. Each ADC data output is internally connected to two digital down converters. In addition to the DDC blocks, the AD9680 has several functions that simplify the automatic gain control function in a communications receiver.

AD9680 14-Bit, 1GSPS Dual ADC

Analog Devices AD9680 Dual, 14-Bit, 1GSPS Analog-to-Digital Converter is 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.
