2.7V至5.5V140微米A軌到軌輸出在采用12位數(shù)模轉(zhuǎn)換器AD5320數(shù)據(jù)表

　　The AD53201 is a single， 12-bit buffered voltage out digital-toanalog converter （DAC） that operates from a single 2.7 V to 5.5 V supply consuming 115 μA at 3 V. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5320 utilizes a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI?， QSPI?， MICROWIRE? and digital signal processing （DSP） interface standards. The reference for AD5320 is derived from the power supply inputs and thus gives the widest dynamic output range. The part incorporates a power-on reset circuit that ensures that the DAC output powers up to zero volts and remains there until a valid write takes place to the device. The part contains a powerdown feature that reduces the current consumption of the device to 200 nA at 5 V and provides software selectable output loads while in power-down mode. The part is put into powerdown mode over the serial interface.
