Analog Devices Expands Low-Power Data Converter Portfolio
New 16-bit, low-power, high-speed ADCs include three industry technology firsts in error correction, speed
with 26 High-Speed ADCs
26, 2009 -- NORWOOD, Mass.
)-- Analog Devices, Inc. (NYSE: ADI), the global leader in data-conversion technology for signal
processing applications, expanded its low-power data converter portfolio with 26 ADCs (analog-to-digital
converters) for effective high-performance, power-efficient communications, portable device, instrumentation and
The offering includes three data converter technology industry firsts for 16-bit
, the industry’s first 16-bit 80MSPS low-power, dual ADC with quadrature-error
, the industry’s first single-channel, 16-bit low-power ADC spanning 80 to 125 MSPS
, the industry’s smallest, single-channel 16-bit low-power ADC spanning 20 to 80 MSPS.
These new ADC
products provide designers a flexible, future-proof platform to differentiate their systems without changing the
core design by migrating either resolution or bandwidth support by means of space efficient pin compatible
families. In addition, the new ADCs’ energy efficiencies provide significant power consumption improvement without
impacting system-level performance.
In addition to the
flagship converters and their various speed grades, ADI introduced today 23 single-channel low-power
ADCs, bringing the number of
low power data converters
ADI has brought to market in the last 180 days to 44*. The power consumption
savings across these ADCs is as high as 87% compared to equivalent competitive offerings operating comparable ADC
functions. Industry First: Sub 100 mW/Channel, Low-Power, Dual-Channel ADC Spans 20 to 80 MSPS
16-bit low-power ADC consumes 93 mW per channel, which is 6.5 times lower than competing devices. The
is a monolithic, dual-channel 16-bit, 20/40/65/80 MSPS ADC, featuring a high performance
sample-and-hold circuit and on-chip voltage reference. It’s also the industry’s first 16-bit ADC family to include
a QEC and DC offset digital processing block. These blocks dynamically minimize the errors produced in an
in-phase/quadrature (I/Q) complex signal receiver system. By using the QEC block, system designers can relax
component matching requirements by reducing gain and phase errors due to component mismatches. The net result can
also enable a more robust receiver design. In addition, the DC-offset algorithm minimizes offsets commonly found
in DC-coupled applications. The product uses multistage differential pipeline architecture with output error
correction logic to provide 16-bit accuracy at 80-MSPS data rates and guarantees no missing codes over the full
operating temperature range. The ADC operates from a 1.8-V supply and contains several features designed to
maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable
digital-test-pattern generation. Samples are available now with production quantities available in January, 2010.
Industry First: Low-Power, Single-Channel 16-bit ADC Clocks at 125 MSPS
low-power, 16-bit ADC was designed to support communications applications requiring low
bill-of-material costs, small size, and flexibility. Consuming only 370 mW, this breakthrough in power consumption
represents a 51 percent savings compared to competitive low-power solutions. The ADC core features a multistage,
differential pipelined architecture with integrated output error correction logic. The
features a wide bandwidth differential sample-and-hold analog input amplifier supporting a variety of
user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer
provides means to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain
excellent performance. The ADC output data are either parallel 1.8 V CMOS or 1.8 V LVDS (DDR). Flexible power-down
options allow significant power savings, when desired. Programming for setup and control are accomplished using a
3-bit SPI-compatible serial interface. Production quantities are available now. Industry First:
Smallest 16-bit Low-power, Single-channel ADC Spans 20 to 80 MSPS
16-bit, low-power ADC is available in a small 5 mm x 5 mm package, and the pin-out supports
resolutions from 10 to 16 bits. The low-power, multistage ADC core is based on a proprietary, high-performance,
sample-and-hold circuit and on-chip voltage reference. The product uses a differential-pipeline architecture with
output-error-correction logic to provide 16-bit accuracy at 80 MSPS data rates and guarantees no missing codes
over the full operating temperature range. The ADC contains several features designed to maximize flexibility and
minimize system cost, such as programmable clock and data alignment and programmable digital test pattern
generation. The available digital test patterns include built-in deterministic and pseudorandom patterns, along
with custom user-defined test patterns entered via the SPI. A differential clock input controls all internal
conversion cycles. An optional DCS compensates for wide variations in the clock duty cycle while maintaining
excellent overall ADC performance. The digital output data are presented in offset binary, Gray code, or twos
complement formats at double-data-rate low-voltage CMOS levels. A data output clock (DCO) is provided to ensure
proper latch timing with receiving logic. Samples are available now with production quantities available in
January, 2010. Pricing, Tools and Complimentary Products
