DescriptionThe AD5530/AD5531 are single 12- and 14-bit (respectively) serial input, voltage output digital-to-analog converters (DAC).
AD5530/AD5531 utilize a versatile 3-wire interface that is compatible
The AD5530 and AD5531 are single 12-/14-bit serial input,voltage output DACs, respectively.
AD5530/AD5531 utilize a versatile 3-wire interface that is compatible with SPI™, QSPI™, MICROWIRE™, and DSP interface standards.Data is presented to the part in the format of a 16-bit serial word.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 AD5530/AD5531 output is buffered by a gain of 2 amplifier and referenced to the potential at DUTGND.LDAC may be used to update the output of the DAC asynchronously. A power-down (PD) pin allows the DAC to be put into a low power state, and aCLR pin allows the output to be cleared to a user-defined voltage, the potential at DUTGND.
The AD5530 and AD5531 are available in 16-lead TSSOP packages.
