AD5308 General Description
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 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 are offered in the same pinout, which allowsusers to select the resolution appropriate for their applicationwithout redesigning their circuit board.
