Product Details
●The AD5689R _nano_DAC+™ is a low power, dual, 16-bit buffered voltage output digital-to-analog converter (DAC). The device includes a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The device operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.
●The AD5689R also incorporates a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. The part contains a per channel power-down feature that reduces the current consumption of the device to 4 μA at 3 V while in power-down mode.
●The AD5689R uses a versatile serial peripheral interface (SPI) that operates at clock rates up to 50 MHz. and contains a VLOGIC pin that is intended for 1.8 V/3 V/5 V logic.
