GENERAL DESCRIPTION
The AD5372/AD5373 contain 32 16-/14-bit DACs in a single
64-lead LQFP. The devices provide buffered voltage outputs with
a nominal span of 4× 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 four groups of
eight 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 1.
The AD5372/AD5373 offer guaranteed operation over a wide
supply range: V
16.5 V. The output amplifier headroom requirement is 1.4 V
operating with a load current of 1 mA.

The AD5372/AD5373 have a high speed serial interface that is
compatible with SPI, QSPI™, MICROWIRE™, and DSP inter-
face standards and can handle clock speeds of up to 50 MHz.
The DAC registers are updated on reception of new data. All
the outputs can be updated simultaneously by taking the LDAC
input low. Each channel has a programmable gain and an offset
adjust register.
Each DAC output is gained and buffered on chip with respect
to an external SIGGNDx input. The DAC outputs can also be
switched to SIGGNDx via the CLR pin.
