2.5伏到5.5伏500μ四电压输出8/10/12位DAC 10引脚封装ad5304/ad5314/ad5324数据表

　　TheAD5304/AD5314/AD53241 are quad 8-， 10-， and 12-bit buffered voltage outputDACs in 10-lead MSOP and 10-lead LFCSP packages that operatefrom a single 2.5 V to 5.5 V supply， consuming 500 μA at 3 V. Their on-chip output amplifiersallow rail-to-rail output swing to be achieved with a slew rate of 0.7 V/μs. A 3-wire serial interface is used; it operates at clock rates up to 30 MHz and is compatible with standard SPI， QSPI， MICROWIRE， andDSPinterface standards. The references forthe four DACs are derived from one referencepin. The outputs of all DACscanbe updatedsimultaneously using the software LDAC function. The parts incorporate a power-on reset circuit， and ensure that the DAC outputs power up to 0 V and remains there until a valid write takes place to the device. The parts contain a power-down feature that reduces the current consumption of the device to 200 nA @ 5 V （80 nA @ 3 V）。 The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 3 mW at 5 V， 1.5 mW at 3 V， reducing to 1 μW in power-down mode
