AD5316R Quad 10-Bit nanoDAC® with 2 ppm/°C Reference, I2C Interface

The AD5316R incorporates a power-on reset circuit and a RSTSEL pin; the RSTSEL pin ensures that the DAC outputs power up to zero scale or midscale and remain at that level until a valid write takes place. The part contains a per-channel power-down feature that reduces the current consumption of the device in power-down mode to 4 µA at 3 V. The AD5316R 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 Excellent DC Performance: Total Unadjusted Error:±0.1% of FSR maximum Low Drift On-Chip Reference: 2.5V, 2 ppm/°C typical temperature coefficient Two Package Options:3 mm × 3 mm, 16-lead LFCSP or 16-lead TSSOP Applications Digital Gain and Offset Adjustment Programmable Attenuators Industrial automation Data acquisition systems

The AD5316R, a member of the nano DAC® family, is a quad, 10-bit buffered voltage output DAC. 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 package and in a TSSOP package.
