They operate from a single 2.5 V to 5.5 V supply, consuming 0.7 m A typical at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/μs. The AD5308/ AD5318/AD5328 use a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is patible with standard SPI, QSPI, MICROWIRE, and DSP interface standards. The references for the eight DACs are derived from two reference pins (one per DAC quad). These reference inputs can be configured as buffered, unbuffered, or VDD inputs. The parts incorporate a power-on reset circuit, which ensures that the DAC outputs power up to 0 V and remain there until a valid write to the device takes place. The outputs of all DACs may be updated simultaneously using the asynchronous LDAC...
