Preliminary Technical Data
AD5372/AD5373
General Description
The ADAD5372/AD5373 has a high-speed serial interface,
which is compatible with SPI®, QSPI™, MICROWIRE™, and DSP
interface standards and can handle clock speeds of up to 50
MHz.
The AD5372 and AD5373 contain 32, 16-bit or 14-bit DACs in
a single, 56-lead, LFCSP or 64-lead LQFP package. The
AD5372/AD5373 provides buffered voltage outputs with a span
4 times the reference voltage. The gain and offset of each DAC
can be independently trimmed to remove errors. For even
greater flexibility, the device is divided into 4 groups of 8 DACs.
Two offset DACs allow the output range of the groups to be
altered. Group 0 can be adjusted by Offset DAC 0, and group 1
to group 3 can be adjusted by Offset DAC 2.
The DAC outputs are updated on reception of new data into the
DAC registers. All the outputs can be updated simultaneously
LDAC
by taking the
input low. Each channel has a program-
mable gain and an offset adjust register.
Each DAC output is gained and buffered on-chip with respect
to an external SIGGND input. The DAC outputs can also be
The ADAD5372/AD5373 offers guaranteed operation over a
wide supply range with VSS from -4.5 V to -16.5 V and VDD
from+8 V to +16.5 V. The output amplifier headroom
requirement is 1.4 V operating with a load current of 1 mA.
