The AD5308/AD5318/AD5328 are octal 8-, 10-, and 12-bitbuffered voltage output DACs in a 16-lead TSSOP. They operatefrom a single 2.5 V to 5.5 V supply, consuming 0.7 mA typ at 3 V.Their on-chip output amplifiers allow the outputs to swingrail-to-rail with a slew rate of 0.7 V/s. The AD5308/AD5318/AD5328 use a versatile 3-wire serial interface that operates atclock rates up to 30 MHz and is compatible with standardSPI, QSPI, MICROWIRE, and DSP interface standards.
The references for the eight DACs AD5308/AD5318/AD5328 are derived from two referencepins (one per DAC quad). These reference inputs can beconfigured as buffered, unbuffered, or VDD inputs. The partsincorporate a power-on reset circuit, which ensures that the DACoutputs power up to 0 V and remain there until a valid write tothe device takes place. The outputs of all DACs may be updatedsimultaneously using the asynchronousLDAC input. The partscontain a power-down feature that reduces the current consumptionof the devices to 400 nA at 5 V (120 nA at 3 V). The eightchannels of the DAC may be powered down individually.
All three parts AD5308/AD5318/AD5328 are offered in the same pinout, which allowsusers to select the resolution appropriate for their applicationwithout redesigning their circuit board.
