Low-Power 14-bit A/D Converters Enable High-Performance, Multi-Channel Data Acquisition in Compact Package

8- and 16-channel A/D converters address space
constraints in industrial, medical and communications designs.
Analog Devices, Inc. (NASDAQ: ADI) introduced today two 14-bit
A/D converters that provide the lowest power in the smallest
package size in their class. In industrial ultra-sound and
instrumentation, healthcare imaging, military countermeasure and
communications receiver applications, the 16-channel, 65-MSPS
AD9249 and the 8-channel, 125-MSPS AD9681 A/D converters meet
designer needs for high-performance, multi-channel data acquisition
at low power where a small package size is crucial to the overall
design.
The AD9249 integrates 16 A/D converter channels into a single
package and dissipates 58 mW of power per channel at 65 MSPS, which
reduces thermal concerns in high-channel-count designs. The
8-channel AD9681 dissipates 110 mW per channel at 125 MSPS. Both
converters are available in a compact 10-mm x 10-mm package,
feature on-chip sample-and-hold circuit and achieve a spurious free
dynamic range greater than 90dBc and signal-to-noise ratio of 74
dBFS or better.
In addition to low power and a small footprint, the AD9249 and
AD9681 A/D converters are easy to use with data clock outputs
(DCO±1, DCO±2) that operate at frequencies of up to 500 MHZ and 455
MHz respectively and support double-data-rate operation. They
require a single 1.8 V power supply and an LVPECL-/
CMOS-/LVDS-compatible sample rate clock for full performance
operation. No external reference or driver components are required
for many applications.
