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.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
EXPLANATION OF TEST LEVELS
I. 100% production tested.
II 100% production tested at 25°C and sample tested at
specified temperatures.
III. Sample tested only.
IV. Parameter is guaranteed by design and characterization
testing.
V. Parameter is a typical value only.
100% production tested at 25°C; guaranteed by design and
characterization testing for industrial temperature range; 100%
production tested at temperature extremes for military devices.
OPERATING RANGE
Operating ambient temperature range: 0°C to 70°C. See the
Thermal Considerations section.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
