AD5697R Dual 12-Bit nanoDAC+™ with 2 ppm/°C Reference, I2C Interface

The AD5697R uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz, and includes a VLOGIC pin intended for 1.8 V/3 V/5 V logic. PRODUCT HIGHLIGHTS Precision DC Performance: TUE: ±0.1% of FSR max Low Drift 2.5 V On-Chip Reference: 2 ppm/°C typical temperature coefficient Tiny Package: 3 mm × 3 mm, 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 AD5697R nanoDAC+™ is a dual, 12-bit, voltage output DACs. The device includes a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (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 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5697R also incorporates a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Each part contains a per-channel power-down feature that reduces the current consumption of the device to 4 μA at 3 V while in power-down mode.
