GENERAL DESCRIPTION
The AD5530/AD5531 are single 12- and 14-bit (respectively)
serial input, voltage output digital-to-analog converters (DAC).
They utilize a versatile 3-wire interface that is compatible with
SPI, QSPI, MICROWIRE, and DSP interface standards. Data
is presented to the part in a 16-bit serial word format. Serial
data is available on the SDO pin for daisy-chaining purposes.
Data readback allows the user to read the contents of the DAC
register via the SDO pin.
The DAC output is buffered by a gain of two amplifier and
referenced to the potential at DUTGND. LDAC can be used to
update the output of the DAC asynchronously. A power-down
pin (PD) allows the DAC to be put into a low power state, and
a CLR pin allows the output to be cleared to a user-defined
voltage, the potential at DUTGND.
The AD5530/AD5531 are available in 16-lead TSSOP.
