AD3541R
Single Channel, 12-/16-Bit, 16 MUPS, Multispan, Multi-IO SPI DAC
FEATURES
GENERAL DESCRIPTION
► 12-/16-bit resolution
The AD3541R is a low drift, single channel, ultra-fast, 12-/16-bit ac-
curacy, voltage output digital-to-analog converter (DAC) that can be
configured in multiple voltage span ranges. The AD3541R operates
with a fixed 2.5 V reference.
► 16 MUPS single channel rate in fast mode
► 11 MUPS single channel rate in precision mode
► 78 ns small signal settling time to 0.1% accuracy
► 100 ns large signal settling time to 0.1% accuracy
► Ultrasmall glitch: <50 pV×s
► Ultralow latency: 5 ns
► THD: −105 dB at 1 kHz for AD3541R-16 and −95 dB at 1 kHz for
AD3541R-12
Each DAC incorporates three drift compensating feedback resistors
for the internal transimpedance amplifier (TIA) that scales the
output voltage. The device has five preconfigured output voltage
ranges: 0 V to 2.5 V, 0 V to 5 V, 0 V to 10 V, −5 V to +5 V, and −2.5
V to +7.5 V.
The AD3541RBCPZ16 (hereafter referred to as AD3541R-16) can
operate in fast mode for maximum speed or precision mode for
maximum accuracy. The AD3541RBCPZ12 (hereafter referred to as
AD3541R-12) has a single operation mode.
► 5 selectable output voltage ranges
► 1.2 V and 1.8 V logic level compatible
► Single (classic) and dual SPI modes
► Multiple error detectors, both analog and digital domains
► 2.5 V internal voltage reference, 10 ppm/°C maximum TC
► Small package: 4 mm × 4 mm LFCSP
The serial peripheral interface (SPI) can be configured in dual SPI
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.
APPLICATIONS
The AD3541R is specified over the extended industrial temperature
range (–40°C to +105°C).
