Quad, 12-Bit nanoDAC+ with 2 ppm/°C On-Chip Reference and SPI Interface
The AD5684R nanoDAC+TM 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 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.
- High Relative Accuracy: AD5684R (12-bit): ±1LSB INL max

- Tiny Package: 3mm × 3mm 16 lead LFCSP or 16 lead TSSOP
- Optical transceivers
- Base-station power amplifiers
- Process control (PLC I/O cards)
- Industrial automation
- Data acquisition systems
