四， 16位/ 14位/ 12位属于nanoDAC Quad, 16-/14-/12-Bit nanoDAC
Product Details
The AD5684R _nano_DAC+™ is a quad, 12-bit, rail-to-rail, voltage output DAC. The device includes a 2.5V, 2ppm/˚C internal reference enabled by default and a gain select pin giving a full-scale output of 2.5V gain=1 or 5V 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 1.5mV offset error performance. The device is available in a 3mm X 3mm LFCSP and a TSSOP package.
The AD5684R also incorporates a power-on-reset circuit and a RSTSEL pin that ensures the DAC outputs power up to zero-scale or midscale, and remain there until a valid write takes place. Each device contains a per-channel power-down feature that reduces the current consumption of the device to 4 uA at 3 V while in power-down mode.
The AD5684R employs a versatile SPI interface that operates at clock rates up to 50 MHz and includes a VLOGIC pin intended for 1.8V/3V/5V logic.
