GENERAL DESCRIPTION
The AD10678 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. Only a single analog input and PECL
sampling clock, as well as 3.3 V and 5 V power supplies, are
required.
The AD10678 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
this connector from Samtec: FSI-110-03-G-D-AD-K-TR. The
overall card fits a 2.2" × 2.8" PCB specified from 0°C to 70°C.
PRODUCT HIGHLIGHTS
1. Guaranteed sample rate of 80 MSPS.
2. Input signal conditioning with optimized noise
performance.
3. Fully tested and guaranteed performance.
