2.7至5.5伏250μ轨到轨输出16位DAC纳米在SOT-23的AD5662数据表
分享资料个
The AD5662， a member of the nanoDAC family， is a low power， single， 16-bit buffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5662 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V （AD5662x-1） or to midscale （AD5662x-2）， and remains there until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode. The low power consumption of this part in normal operation makes it ideally suited to portable battery-operated equipment. The power consumption is 0.75 mW at 5 V， going down to 2.4 μW in power-down mode. The AD5662’s on-chip precision output amplifier allows rail-torail output swing to be achieved. For remote sensing applications， the output amplifier’s inverting input is available to the user. The AD5662 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz， and is compatible with standard SPI®， QSPI™， MICROWIRE™， and DSP interface standards.
