FEATURES 80 MSPS sample rate 80 dBFS signal-to-noise ratio Transformer-coupled analog input Single PECL clock source Digital outputs True binary format 3.3 V and 5 V CMOS-compatible APPLICATIONS Low signature radar Medical imaging Communications instrumentation Instrumentation Antenna array processing GENERAL DESCRIPTION The AD10678 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 AD10678 is assembled using a 0.062-inch laminate board with three sets of connector interface pads to accommodate analog and digital isolation. Analog Devices recommends using the FSI-110-03-G-D-AD-K-TR connector from Samtec. The overall board fits a 2.2 inch × 2.8 inch PCB specified from 0°C to 70°C.
