GENERAL DESCRIPTION
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
analog and digital isolation. Analog Devices recommends
using the FSI-110-03-G-D-AD-K-TR connector from Samtec.
The overall card fits a 2.2 inch × 2.8 inch PCB specified from
0°C to 70°C.
