GENERAL DESCRIPTION
The AD10677 is a 16-bit, high performance, analog-to-digital
converter 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 are required as well as 3.3 V and 5 V power supplies.
The AD10677 is assembled using a 0.062" thick 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 "脳 2.8" PCB specified from 0擄C to 70擄C.
PRODUCT HIGHLIGHTS
1. Guaranteed sample rate of 65 MSPS.
2. Input signal conditioning with optimized noise performance.
3. Fully tested and guaranteed performance.
