16/14/12位SPI纳米DAC和2 LSB INL理论参考ad5683r/ad5682r/ad5681r/ad5683数据表

　　The AD5683R/AD5682R/AD5681R/AD5683， members of the nanoDAC+® family， are low power， single-channel， 16-/14-/12-bit buffered voltage out digital-to-analog converters （DACs）。 The devices， except the AD5683， include an enabled by default internal 2.5 V reference， offering 2 ppm/°C drift. The output span can be programmed to be 0 V to VREF or 0 V to 2 × VREF. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The devices are available in a 2.00 mm × 2.00 mm， 8-lead LFCSP or a 10-lead MSOP. The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. The AD5683R/AD5682R /AD5681R/AD5683 contain a power-down mode that reduces the current consumption of the device to 2 µA （maximum） at 5 V and provides software selectable output loads while in powerdown mode. The AD5683R/AD5682R/AD5681R/AD5683 use a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz. Some devices also include asynchronous RESET pin and VLOGIC pin options， allowing 1.8 V compatibility.
