AD3552R
Dual Channel, 16-Bit, 33 MUPS, Multispan, Multi-IO SPI DAC
FEATURES
GENERAL DESCRIPTION
► 16-bit resolution
► 33 MUPS rate in fast mode
► 22 MUPS rate in precision mode
► 65 ns small signal settling time to 0.1% accuracy
► 100 ns large signal settling time to 0.1% accuracy
► Ultra small glitch: < 50 pV×s
The AD3552R is a low drift, dual channel, ultra-fast, 16-bit accura-
cy, current output digital-to-analog converter (DAC) that can be
configured in multiple voltage span ranges. The AD3552R operates
with a fixed 2.5 V reference.
Each DAC incorporates three drift compensating feedback resistors
for the required external transimpedance amplifier (TIA) that scales
the output voltage. Offset and gain scaling registers allow for
generation of multiple output span ranges, such as 0 V to 2.5 V, 0 V
to 5 V, 0 V to 10 V, −5 V to +5 V, and −10 V to +10 V, and custom
intermediate ranges with full 16-bit resolution.
► Ultra low latency: 5 ns
► THD: −105 dB at 1 kHz
► Highly configurable output voltage span and offset
► 1.2 V and 1.8 V logic level compatible
► Single (classic), dual, and quad SPI modes
► Multiple error detectors, both analog and digital domains
► 2.5 V internal voltage reference, 10 ppm/°C maximum tempera-
ture coefficient
The DAC can operate in fast mode for maximum speed or precision
mode for maximum accuracy.
The serial peripheral interface (SPI) can be configured in quad SPI
mode, dual synchronous SPI mode, dual SPI mode, and single SPI
(classic SPI) mode with single date rate (SDR) or double data rate
(DDR), with logical levels from 1.2 V to 1.8 V.
► 5 mm × 5 mm LFCSP
APPLICATIONS
The AD3552R is specified over the extended industrial temperature
range (–40°C to +105°C).
