AD5686R:  Quad, 16-Bit nanoDAC+™ with 2 ppm/°C On-Chip Reference and SPI Interface

Product Details

Product Status:Recommended for New Designs

The AD5686R nanoDAC+TM is a quad, 16-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 AD5686R 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 AD5686R 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.
