Analog Devices Introduces Eight High-Speed,
Low-Power Digital-To-Analog Converters
Dual-channel transmit DACs use 40 percent less power and are
one-third the size of competing devices, yielding power savings in communications,
industrial and instrumentation equipment.
NORWOOD, Mass.--(BUSINESS
WIRE)-- Analog Devices, Inc. (NYSE:
ADI), the global leader in data conversion technology, is helping
electronic equipment manufacturers design more energy-efficient products
with the introduction today of eight
TxDAC® transmit digital-to-analog converters (DACs), each integrating
two DACs on a single device. Adding to ADI’s extensive
high-speed DAC portfolio, the new pin-compatible
dual TxDAC converters are designed for communications, industrial,
instrumentation and other demanding high-performance applications for
which low power consumption and space savings yield significant cost,
performance and time-to-market advantages. Dissipating only 220 mW at
their maximum sample rate, the
AD911x series of dual TxDAC devices consume 40 percent less power
and are one-third the size of competing transmit DACs, while achieving
10 dB better SFDR (spurious-free dynamic range) performance. The
AD971x series of dual TxDAC devices, with 2-mA full-scale output
current, are even more energy efficient, consuming 70 percent less power
than competing solutions.
“With the industry increasingly focused on efficiency and portability,
design engineers are being squeezed to reduce power consumption and
board space in their designs,” said David Robertson, product line director
for the High Speed Signal Processing group, Analog Devices. “Whether
they’re designing femtocell base stations, battery-powered instrumentation
or medical applications, designers are looking for new DAC products
that will help them meet their space and power budgets, without sacrificing
performance.”
Low Power, Integration and Flexibility
Each new TxDAC integrates two 14-, 12-, 10- or 8-bit digital-to-analog
converters with sample rates up to 125 MSPS (mega-samples-per-second).
These devices allow designers to adjust the full-scale current from
1 to 4 mA or 4 to 20 mA with a single, pin-compatible architecture and
common software code.
The AD971x TxDAC series features 1- to
4-mA maximum differential output current. Power dissipation at 2 mA
output current is only 37 mW at 10 MSPS and 53 mW at 50 MSPS. This is
one-third that of competing transmit DACs, making the new series ideal
for small, limited range wireless equipment, such as picocell and femtocell
base stations and battery-powered medical, industrial and instrumentation
applications.
The AD911x TxDAC series has 4- to 20-mA maximum
differential output current. It dissipates 40 percent less power than
other devices in its class and is suited to automotive, medical, instrumentation
and communications applications where channel densities must be maximized
without the addition of cooling fans or where environmental considerations
are driving a reduction in power consumption. The AD911x devices achieve
85-dB SFDR to 10 MHz, which is superior to other devices in its class.
Despite their small 6 mm x 6 mm package size, the new DACs are loaded
with performance features, such as an internal calibrator for improved
INL and DNL performance up to a 10-MHz output frequency, an internal
voltage reference, independent full-scale current control, on-chip load
and common-mode resistors, and a pair of auxiliary DACs that can be
used for generating control voltages or for system calibration.
The new TxDAC devices offer a seamless interface to ADI’s high-performance
quadrature modulators, such as the
ADL5370. If a single-ended or differential-buffered voltage output
is needed, then the
ADA4899-1 and
ADA4841-2 operational amplifiers are excellent choices, respectively.
Additionally, Analog Devices’ high speed converters, such as the AD911x
TxDAC family, are designed to operate seamlessly with ADI’s
AD9513 clock distribution IC and new line of voltage regulators,
including the
ADP3334 and
ADP3333.
Pricing and Availability
The TxDACs are
available now in volume production. The devices come in a small, 6 mm
× 6 mm, Pb-free, 40-lead LFCSP (lead-frame chip-scale package).
