AD5684R Series

The AD5684RnanoDAC+™ 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 VLOGICpin intended for 1.8V/3V/5V logic.PRODUCT HIGHLIGHTSHigh relative accuracy: AD5684R (12-bit): ±1LSB INL maxLow drift on-chip reference: 2.5V, 2ppm/°C temperature driftTwo package options: 3mm × 3mm 16-lead LFCSP or 16-lead TSSOPAPPLICATIONSOptical transceiversBase-station power amplifiersProcess control (PLC I/O cards)Industrial automationData acquisition systems
