Analog Devices has extended its range of high density, high
performance, multichannel DACs—the denseDAC family—by
offering new, bipolar, 8-channel to 40-channel, 16-bit and 14-bit
DACs. The patented iCMOS™ industrial manufacturing process
enables the combination of up to 40 channels, high resolution, and
±10 V output range, in a compact footprint, packed with a range of
new integrated programmable features.
But did you know the range of applications that these flexible parts
can support and enhance? ADI engineers have found innovative
ways to optimize for target application areas, addressing the needs
of ATE, optical communications and networking, industrial, and
precision instrumentation applications. Products are designed with
your system needs in mind, so the denseDAC family is certain to
have a solution that matches your requirements.

AD5362 in PLC Applications
5V REFERENCE
PLC applications will benefit from the precision, integration, and
flexibility offered by the denseDAC family, more specifically the
AD5362. With eight channels and 16-bit monotonic performance,
this ±10 V DAC in 8 mm × 8 mm LFCSP also integrates
user-programmable offset and gain registers per channel, and userselectable output voltages. The programmable output span of 20 V
provides greater freedom to customize products, without the need
for complex external analog circuitry. The AD5362 also includes
a temperature sensor, a thermal monitor mode, a voltage monitor
multiplexer, and a power-down mode—all of which are advantageous
in system monitoring. The other members of this family are pincompatible solutions, allowing higher channel or lower resolution
upgrade path with no design change.

AD5360 in Instrumentation Applications
The AD5360 is a highly integrated, 16-channel, ±10 V, serial input, voltage output DAC. It provides industrial and instrumentation system
designers the flexibility, functionality, and space efficiency that are key to implementing voltage level setting, closed-loop control, and coarse/
fine tune circuits. It combines 16-bit resolution, ±4 LSB INL, user-programmable offset and gain registers per channel, and user-selectable
output voltage ranges in 8 mm × 8 mm LFCSP footprint. Additional features include SPI with readback and PEC, temperature sensor, toggle
mode, and power-down mode. These devices enable the integration of greater functionality into smaller board space, which is particularly
important in precision instrumentation applications such as oscilloscopes, data generators, and medical equipment.

AD5370 in ATE Applications
In ATE applications several DACs are required to control pin drivers, comparators, PMUs, and signal timing. Traditionally, sample-and-hold
devices were used. However, DACs have several advantages: no refreshing is required, there is no droop, pedestal error is eliminated, and
there is no need for external filtering to remove glitches. The AD5370 is a 40-channel DAC offering 16-bit DNL and 14-bit INL, in 9 mm × 9 mm
LFCSP, thereby providing the channel density and performance required by high precision ATE pin electronics.

AD5382 in an Optical Attenuator Application (OADM System)
The AD5382, with its 32-channel, 14-bit monotonic performance and high level of integration, is ideally suited for optical applications.
In optical attenuator applications, such as dynamic gain equalizers, variable optical attenuators (VOA), and optical add-drop multiplexers
(OADM), each wavelength is individually extracted using an arrayed wave guide (AWG). Its power is monitored using a photodiode,
transimpedance amplifier, and an ADC in a closed-loop control system. Here the AD5382 controls the optical attenuator for each wavelength,
ensuring that power is equalized in all wavelengths before being multiplexed onto the fiber. This prevents information loss and saturation
from occurring at amplification stages farther along the fiber.

Evaluation Boards
Evaluation boards are available for denseDAC products. These are complete self-contained evaluation tools for precision
converters. These boards essentially allow development engineers to evaluate the features, functions, and performance of
the devices to determine suitability for end user applications. Evaluation boards interface directly to the PC and come with
a suite of software designed to allow simple control of all programmable functions.
