AD5695R Quad, 14-Bit nanoDAC+ with 2 ppm/°C On-Chip Reference and I2C Interface

High Relative Accuracy: AD5695R (14-bit): ±1LSB INL max Low drift on-chip reference: 2.5V, 2ppm/°C temperature drift Tiny Package: 3mm × 3mm 16-lead LFCSP or 16-lead TSSOP Applications Optical transceivers Base-station power amplifiers Process control (PLC I/O cards) Industrial Automation Data acquisition systems

The AD5695R nanoDAC+TM is a quad, 14-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 AD5695R 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 AD5695R employs an I2C interface that operates at clock rates up to 400 kHz and includes a VLOGIC pin intended for 1.8V/ 3V/ 5V logic.
