The AD10677 is a 16-bit high performance analog-to-digital converter (ADC) for applications that demand increased SNR levels. Exceptional noise performance and a typical signal-to-noise ratio of 80 dBFS are obtained by digitally postprocessing the outputs of four ADCs. A single analog input and PECL sampling clock and 3.3 V and 5 V power supplies are required. The AD10677 is assembled using a 0.062-inch laminate board with three sets of connector interface pads to accommodate a variety of interfaces, providing flexibility for a wide range of applications.
