Analog Devices’ High Performance Output
Drivers Increase Efficiency of Industrial and Process Control Systems
-
ADI’s new output drivers offer
best-in-class performance with industry’s
highest level of accuracy and diagnostic capability.
NORWOOD, Mass. (Business Wire EON) May 12, 2008 --
Analog Devices, Inc. (ADI), a world leader in semiconductors for signal
processing applications, today introduced two analog output drivers that
significantly improve the efficiency and reliability of process control
applications, including those operating with high compliance voltages
and temperatures. Using technological advancements enabled by ADI’s
iCMOS™
industrial process technology, the AD5750 and AD5751 output drivers
achieve a three-fold improvement in accuracy over competing solutions,
providing an accuracy level of 0.1 percent TUE (total unadjusted error)
under all operating conditions. The devices condition the output of a
low-voltage, single-supply DAC
(digital-to-analog converter) to provide high performance voltage- and
current-output-drive capability, enabling system design engineers to
deliver more reliable, cost-efficient industrial equipment while using
less board space.
Designed to meet the growing demand for highly configurable industrial
automation controllers, the new output drivers offer extensive
diagnostic functionality such as fault detection and enhanced sensing
capabilities that make system startup and troubleshooting easier.
Integrating user-programmable current- and voltage-output capabilities,
the AD5750 and AD5751 output drivers are ideally suited for programmable
logic controllers, distributed control, and high-voltage analog I/O
systems.
“Analog Devices’
output drivers provide a complete solution for single- and multi-channel
analog I/O systems, meeting the growing demand for feature-rich, highly
reliable process control equipment,” said Mike
Britchfield, product line director, precision signal processing, Analog
Devices. “These devices offer industrial
designers a high-performance system that provides best-in-class drift
and stability specifications, helping to increase plant efficiency and
lower maintenance costs. Plus, the advanced diagnostics make
troubleshooting quick and easy.”
About the AD5750 and AD5751 Output Drivers
The single-channel AD5750 and AD5751 are complete analog output drivers
for industrial and process control applications and eliminate the need
for additional external components such as shunt resistors, range
selection, and fault detection circuitry. The devices handle virtually
all standard analog output signaling requirements with selectable
hardware or software programmability. The high performance and accuracy
of the devices satisfy high-end system requirements of 0.1 percent TUE,
5-ppm/degrees C output drift, and 0.01 percent linearity, eliminating
the need for designers to calibrate their systems at multiple
temperatures and supplies to satisfy end system accuracy and stability
specifications. Analog outputs can drive resistive loads up to 1.5
kohms, capacitive loads up to 1 μF, and
inductive loads up to 0.1 henry.
The AD5750, which operates from dual ±12 V to ±24
V supplies, offers four output voltage ranges (0–5
V, 0–10 V, ±5 V, ±10
V) and five output current ranges (4–20 mA, 0–20
mA, 0–24 mA, ±20
mA, ±24 mA), with 20 percent over-range
capability.
The AD5751 operates from a single 10.8-V to 60-V supply, facilitating
reliable factory communications over long cables. It offers three output
voltage ranges (0–5 V, 0–10
V, 0–40 V) and three output current ranges (4–20
mA, 0–20 mA, 0–24
mA), with 20 percent over-range capability.
The AD5750 and AD5751 incorporate a 30-MHz serial peripheral interface
(SPI) and power-on reset circuitry and are fully specified over a –40ºC
to +105ºC temperature range. Both devices
integrate packet-error checking (PEC) features that verify the interface
data has been correctly received in the presence of noise, which is
useful in industrial environments where data communication corruption
can occur.
Availability and Pricing
The AD5750 and AD5751 are sampling now, and full production quantities
will be available in November 2008. The devices are housed in 5 mm ×
5 mm LFCSPs (lead-frame chip-scale packages), and priced from $2.45 in
1,000-unit quantities. For more information, visit www.analog.com/pr/AD5750
