Analog Devices Announces Industry’s First Data Converter
- Multichannel, 16-bit digital-to-analog converter drives productivity, energy efficiency, and reliability
with Dynamic Power Control
in process control I/O systems in industrial applications.
Mass.--(BUSINESS WIRE)-- Advances in factory automation, process controls, and industrial instrumentation are
contributing to higher manufacturing productivity and increased output. The sustainability of such advances is
under threat, however, as the density of factory process control systems reaches levels where rising power
consumption and thermal issues are beginning to undermine equipment performance, reliability, and safety. Analog
Devices, Inc. (NYSE: ADI), the leading supplier of data converters and a long-time partner to many of the world’s
largest industrial manufacturers, today introduced a multichannel DAC (digital-to-analog converter) with
innovative dynamic power control circuitry including ADI’s leading dc-to-dc switching converters and diagnostic
features. This new DAC can enable increased system productivity, while simultaneously lowering power use without
affecting safety and reliability. Watch the

Dynamic Power Control Reduces Power Loss and Self-Heating
ADI’s highly integrated
AD5755 data converter is a complete, multichannel
control IC (integrated circuit) that incorporates four precision 16-bit DACs with programmable voltage or 4–20-mA
output drivers, along with dynamic power control. The dynamic power control feature works by continually sensing
the load impedance and delivering the required power to the load while minimizing power loss in the rest of the
system. This reduces self-heating and temperature elevation. The unparalleled combination of features and
performance supports four times more channels than any other integrated converter, enabling up to four times more
terminals at twice the performance in a single analog I/O module. The new converter also lowers power consumption
by 80 percent and net thermal rise (silicon temperature minus ambient temperature) by 75 percent compared to other
control driver technologies.
“Increased terminal density puts pressure on module size and can result in
extra heat generation in industrial systems,” said Mike Britchfield, vice president for the Industrial and
Instrumentation Group, Analog Devices. “By reducing power consumption and self-heating, the dynamic power control
function of the
AD5755 meets customer requirements for increased
channel density. This allows manufacturers to achieve channel-rich designs without having to increase the form
factor of their systems or back–off on other performance parameters.”
More on the AD5755 Data Converter
AD5755 offers a full channel spec with a maximum
total unadjusted error of 0.05 %, a relative accuracy of ±0.003% max, and does not require system calibration,
which shortens development time and reduces system maintenance costs. In addition, the single chip architecture
combines multiple converters, power management, linear and other functions, increasing MTTF (mean time to failure)
and improving reliability. Also included are various diagnostics for real-time fault analysis, including
communication, connection, and interface alerts, which simplify the design task and boost operational up-time.
The device, which supports standard industrial voltage and current output ranges, can be used with standard HART
(Highway Addressable Remote Transducer) protocol modems. Also integrated on-chip is a 5-ppm/°C internal reference,
user-accessible offset and gain registers and a 30-MHz SPI (serial peripheral interface) compatible interface. The
device is specified over the extended industrial temperature range of –40°C to +105°C and is housed in a 9 mm × 9
mm LFCSP (lead-frame chip scale package). To download the data sheet, click here.
