Analog Devices Unveils Continuous-Time Sigma-Delta Analog-to-Digital
Converter Family
ADI’s new converter family optimizes bandwidth and resolution to
deliver the industry’s best combination of operating frequency, dynamic
range and signal-to-noise ratio.
NORWOOD, Mass.--(BUSINESS
WIRE)-- Analog Devices, Inc. (NYSE:
ADI), the global
leader in data converter technology, unveiled today its
continuous-time sigma-delta (CTSD) converter architecture for
wireless infrastructure,
medical and other high-performance equipment demanding uncompromised
data resolution and wide bandwidth. The 16-bit,
AD9261 and
AD9262 CTSD converter, and the
AD9267 CTSD modulator couple the industry’s lowest noise and high
dynamic range with a bandwidth of up to 10 MHz.
“Today’s electronics
increasingly rely on data conversion to faithfully translate digital
information to provide the images, voice, audio, video and other real-world
content that defines the quality of the end-user experience,” said Susie
Inouye, research director, Databeans Inc., a leading semiconductor research
firm. “While other architectures have pushed the performance envelope
by offering exceptional throughput, high dynamic range or excellent
low-noise characteristics, continuous-time sigma-delta excels in all
of these areas.”
The highly integrated
CTSD architecture eliminates multiple discrete components at the
system level, while simultaneously improving performance and simplifying
product development.
The AD926x utilizes principles of over
sampling, noise shaping and input characteristics unique to its architecture
to achieve high levels of performance and ease of use. The quiet resistive
input structure relaxes the requirements of the driver amplifier while
the high order over-sampled continuous time loop filter attenuates out-of-band
signals reducing the need for large baseband filters and other signal
conditioning circuitry. The high dynamic range performance reduces or
eliminates the need for automatic gain control in many applications.
These features coupled with a wide input bandwidth simplify system design,
reducing the overall system footprint and shortening time-to-market.
CT-SD ADCs Raise Performance Threshold
The 16-bit single
and dual
AD926x ADC family achieves industry leading performance with an
unprecedented combination of 86-dB dynamic range for an input signal
bandwidth of up to 10 MHz. The highly integrated
AD9261 and
AD9262 feature an on-chip PLL clock multiplier, decimation filters,
and sample rate converters and provide flexible output data rates between
30 MSPS (mega-samples-per-second) and 160 MSPS. The
AD9267, which features only the high-performance 640-MSPS modulator
core and PLL clock multiplier, presents the high speed data directly
to the output. This provides designers the flexibility to offload signal
processing functions to an FPGA or other processor. The 150-mW per channel
to 350-mW per channel power consumption of the new CTSD converters is
matched to a range of communications and industrial applications, including
emerging radio architectures, such as direct down conversion, where
the dual AD9262 or AD9267 can be used to support multiple wireless carriers
and standards simultaneously.
Pricing, Availability and Complementary
Parts
The AD926x CTSD ADC family is sampling now and will be
available in volume production in April 2009. Complementary ADI parts
in the signal chain include the
AD9520 clock generation and distribution integrated circuit and
the high performance
ADL5382 I-Q demodulator.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
