Analog Devices Inc. AD9652 16-Bit Analog-to-Digital Converter (ADC)

Analog Devices Inc. AD9652 16-Bit Analog-to-Digital Converter (ADC) is a dual ADC with sampling speeds of up to 310MSPS. It is designed to support demanding, high speed signal processing applications that require exceptional dynamic range over a wide input frequency range (up to 465MHz). Its exceptional low noise floor of −157.6dBFS and large signal spurious-free dynamic range (SFDR) performance (exceeding 85dBFS, typical) allows low level signals to be resolved in the presence of large signals. The dual ADC cores feature a multistage, pipelined architecture with integrated output error correction logic. A high performance on-chip buffer and internal voltage reference simplify the inter-face to external driving circuitry while preserving the exceptional performance of the ADC.
